The Obamacare Website Rollout: Not What the Doctor Ordered


Software failures can have all sorts of bad consequences, ranging from minor annoyances up to and including death.  On that scale, the very public problems that people currently run into when they try to use the Affordable Care Act's website to buy federally-mandated insurance are somewhere in the middle.  (Since President Obama is on record as having no objection to the term "Obamacare" for the Act, I will use it too from this point on.)  To my knowledge, no one has yet died as a direct consequence of not being able to use the site.  But on the other hand, it's hard to think of another software-related issue that has garnered so much negative publicity in as short a time.  While there is plenty of blame to go around, the question I'm interested in today has to do with the ethics of software engineering, and what lessons this debacle can teach us along those lines.

Software engineering is a relative latecomer to the engineering fold.  There were only a few dozen programmable computers in the world as late as 1950, and the first U. S. undergraduate programs in software engineering were not accredited until 2003.  But few types of engineering involve the average non-technical customer more directly than the design of high-volume websites, which requires strategic and organizational planning as an essential aspect of the overall process. 

According to published reports, the rollout of the www.healthcare.gov website was something of a rush job.  For political reasons, the Oct. 1 deadline could not be postponed, and many changes were being made right up to the last minute.  Finally, there was little time for beta testing with a small group of friendly and informative users who could find problems in time for them to be fixed before the main rollout. 

I am glad I was not one of the people who worked on this website, but I can sympathize with them.  My last major engineering job before deciding to go back to school for my Ph. D. was with a firm that wanted to make cable boxes, the little thing that sits on (or now, under) your TV and selects channels.  The company had never made a large-volume consumer product before.  Up to that time, most of their customers were military and scientific users who paid plenty for a few hand-crafted instruments.  Despite the best efforts of our engineering team, the new box never worked right.  At one point I had a conversation with an older engineer who said, "I'm looking at your group and what I see is a bunch of trapped engineers."  I later learned that the company ended up recalling all the boxes from the field at a cost of six million dollars.  By that time, I was in grad school and dealing with problems of a different sort.   

Sometimes, engineers are placed in an impossible situation where even Superman couldn't deliver the goods as requested, and minimizing damage is about all you can do, at least to start with.  The Obamacare website was a large and complex project that everyone knew would both receive tons of traffic from all sorts of people, most of them technically unsophisticated, and would also draw intense media attention, much of it potentially hostile.  If it had been up to the software engineers, the project might have been "frozen" (no more major changes allowed) up to a year in advance of Oct. 1, and early versions would have gone through beta testing with larger and more varied groups of test subjects with plenty of time to work out the glitches before launch. 

Obviously, that didn't happen.  At the risk of sounding biased, I will state here that the way this project was carried out seems to reflect a mindset which is evident in other actions of the Obama administration.  The President and a circle of powerful like-minded people in the administration have a set of ideas which they all agree on as The Way Things Should Be.  Philosophically, they are idealists in the sense that they start with ideas, and then try to make reality conform to their ideas.  Evidently, the political people in charge of implementing Obamacare were coming up with more ideas for the website right up to the time that it was turned on, and disregarded the hard engineering realities of designing a website that must handle many millions of users who are faced with a fine if they don't sign up for insurance through the site by the end of the year. 

The problem with philosophical idealism is that it sometimes collides with reality, and in such collisions, reality always wins.  In such encounters, idealists may or may not learn the error of their ways.  Of necessity, they end up doing what reality requires them to do, but often in a way that is inefficient, expensive, and more trouble than otherwise.  A new deadline of November 30 has just been announced as the day by which www.healthcare.gov will be working.  Jeffrey Zients, the Chief Performance Officer of the United States, is now in charge of fixing it, and has declared publicly that "Healthcare.gov is fixable."  Any system that is not physically impossible is fixable given enough time and resources, but only time will tell whether Zients and his underlings can get the repairs done on time.

But the rocky startup has added more fuel to the fire of ill feeling that the U. S. public in general harbors toward the federal government.  In a poll by the Pew Research Center for the People and the Press released last week, only 19% of those polled said that they trust the government in Washington to do what is right just about always or most of the time.  Before about 1970, most people did have such trust, but the trend since the early 1960s has been downward, falling below 50% around 1973 (the peak of the Vietnam War) and has risen above 50% since then only once:  right after 9/11/2001 and the first war in Afghanistan.  The fact that most people in the U. S. no longer think that their government can be trusted in this way goes beyond partisan politics to signal deep structural problems in the way power is allocated and used.  This is much more than a problem in engineering ethics, but engineers have to deal with it like everyone else.  And those working on www.healthcare.gov bear a particular responsibility to exhibit leadership in the days to come.

The Theology of Global Warming


Last Saturday, October 19, was the date of the Second Annual Global Frackdown.  In case you didn't hear, the Global Frackdown is an international day of activism on which people who believe that global warming is an oncoming train that's about to knock us silly, gather in groups and protest the oil industry's practice of fracking.  Fracking is a technology that has produced renewed yields from old oil and gas fields and promises to make the United States largely energy-independent in a few years.  But there is no question that fracking leads to the burning of more fossil fuel than otherwise, which is the reason for the Frackdown.  According to the movement's website, there were Frackdown events scheduled even in Texas, where fracking is a native industry and practiced widely.  Opponents of global warming seem to believe in their cause with an almost religious fervor, and for some it may be exactly that:  a substitute religion, complete with a theology, an ethics, and an eschatology that foretells doom for the planet unless we get with the gospel of global warming.

The Frackdown is sponsored by an outfit called 350.org, whose guiding light is one Bill McKibben, a journalist and author of such books as Fight Global Warming Now, Enough, The End of Nature, and Eaarth.  The last title requires a little explanation.  McKibben's basic theme throughout is that humanity has transformed the globe into an artifact (thus The End of Nature).  The rather unfortunate neologism "Eaarth" is McKibben's term for Earth.2, the new thing that isn't really a natural environment anymore, but isn't completely under our control either.  Despite the world's new status as a manufactured product, the laws of physics have not been repealed, and McKibben claims there will be absolutely inevitable bad consequences that will follow if we keep acting as though we were just a slight perturbation in the thing we have historically called Nature.  (Picture a 200-pound St. Bernard who still thinks he is a cute little cuddly puppy and tries to sit in your lap.)  Chief among these perturbations is our burning of fossil fuels such as coal, oil, and gas, which began with the Industrial Revolution and continues to be the single most important energy source worldwide.  McKibben appears to believe as earnestly in the pronouncements of the Intergovernmental Panel on Climate Change (IPCC) as he believes in the Bible (he is a practicing Methodist).  The focus of his most recent efforts has been to sponsor grass-roots movements to give the fossil-fuel industry a bad reputation by means of divestiture movements, Global Frackdowns, and other activist measures sponsored through 350.org.  Why 350?  That is the alleged tipping point of parts per million carbon dioxide in the atmosphere, beyond which innumerable disasters loom.  The current number (as of May 2013) is around 400 ppm, by the way.

I picked up McKibben's Eaarth expecting a uniform challenge to my blood pressure, and for the first two chapters I found what I expected:  a laundry list of terrible things that will happen, and are already happening, because of global warming, which is said to be largely if not exclusively due to anthropogenic carbon dioxide in the air.  Storms, droughts, loss of seacoast regions, die-offs of all kinds, you name it.  So far so bad. 

But then I got to Chapter 3, "Backing Off" and I checked the cover to see if the book was really written by only one author.  McKibben turns out to be what I would call a crypto-distributist.  Distributism, as almost nobody knows, was a short-lived political movement popular in England in the 1930s, whose most well-known exponent was the writer G. K. Chesterton.  Its slogan could have been "smaller, more local, more decentralized," and the old principles of distributism are in perfect harmony with McKibben's plans for us to survive the oncoming global-warming disaster.  For example, here's a problem:  climate change may cause entire monocultures of ag-industry genetically modified foods to disappear.  Solution:  have thousands of independent farmers supply hundreds of different varieties to farmers' markets in cities around the globe, and some of them at least will make it.  Problem:  giant fossil-fueled power grids with a few huge plants are wrecking the environment, and giant nuclear plants to replace them would cost too much.  Solution:  spread solar and other renewable energy sources everywhere so that people can be largely energy-independent down to the city block and house level. 

The biggest change McKibben calls for is not technological but cultural.  He thinks we will have to end our love affair with the super-independent lifestyle so encouraged by American culture and commerce, and live more like we used to, in interdependent communities where not only did you know your neighbors, you depended on them for essential things in your life such as services, goods, and jobs.  Only in this way will we survive the bugbear of climate disasters that await us.

Eaarth is really two books: one written by a frenzied climate-change activist, and another written by a pleasant, earnest Methodist Sunday-school teacher who wants us all to get along together and be good little distributists, but without using that word.  I see no indication that McKibben has even heard of distributism, but most of his solutions lie squarely in that tradition.  And to the extent that they do, I by and large agree with them, although my pragmatic side doubts that McKibben and his fellow activists will be able to make much headway against the powerful entrenched political and economic interests who would like things to stay the way they are now.

To the extent that McKibben gets us to have more to do with our neighbors and less to do with huge multinational corporations, I hope he succeeds.  But he seems to have reached the same desirable conclusions as the English distributists through what seems to me to be a long and unnecessary detour through the notion of global warming and its promised doomsdays, which has almost taken the place of a religion for many people.  If you believe that buying an electric car will make environmental Armageddon 0.0001% less likely, then your faith has convenient ways for you to take actions that are unquestionably righteous, and to condemn those bad actors such as fossil-fuel companies that are unquestionably evil.  But life is seldom that simple, and I hope McKibben writes another book that sets forth more substantial and eternal reasons for people to be more neighborly—and leaves out all that stuff about global warming.

OSHA Fine for West Explosion: What's the Point?


Last April 17, when the West Fertilizer Company's facility in the Texas town of the same name exploded, killing 15 and laying waste not only to the plant but to a good chunk of the town as well, it had been more than 25 years since a federal Occupational Safety and Health (OSHA) inspector personally appeared at the plant.  But that did not stop OSHA from issuing a $118,300 fine against the company last week, on October 9, for a list of 24 safety violations.  This news came out despite the federal government's shutdown because Sen. Barbara Boxer's office found out about it and notified news media.  The company has fifteen days to either pay the fine or file an administrative appeal with OSHA, and company representatives said they were conferring with lawyers about their next step.

Depending on how you view the idea of punishment, OSHA's fine either looks pretty silly or seems like a sound and reasonable step for such an agency to take.  Let's examine the case for silly first.

Suppose you run a small fertilizer company that has gone through bankruptcy in the last few years and probably has total assets, land and facilities included, of at most a few million dollars, with a one-million-dollar liability insurance policy on the property.  Due to causes that even combined federal and state investigations cannot precisely determine, your plant blows up, killing fifteen of your fellow citizens, causing over a hundred million dollars' worth of damage to your town, and by the way, completely demolishing the physical assets of your business.  Half a year later, along comes OSHA and lays a fine of over $100,000 on you for various historical violations based on testimony of how the fertilizer that exploded was stored and for not having an emergency response plan.  How do you respond?

I am not running the West Fertilizer Company, but at the moment, hiring lawyers to file an administrative appeal will be a lot cheaper than paying the fine up front, which would probably suck up most of any remaining cash and possibly make the company go out of business altogether.  Not that they haven't had time to do anything more than deal with lawyers and lawsuits since April anyway.  Obviously, the better time for OSHA to have levied such a fine would have been before the April explosion, when the changes possibly stimulated by such a large penalty might have had the positive effect of preventing the explosion. At this point, the fine brings to mind a scene in the animated film Wallace & Gromit:  The Curse of the Were-Rabbit.  At one point, the brilliant but silent canine character Gromit, a skilled driver, goes on a wild car chase that winds up with his vehicle stalled out after a minor collision.  Sitting there silently on a dark road, Gromit seems lost in the depths of despair, thinking that things cannot possibly get worse.  And then they do:  the car's airbag deploys in his face.  OSHA's fine is timed as well as Gromit's airbag.

Whether the fine makes any sense depends on one's theory of punishment.  In How to Think About the Great Ideas, philosopher Mortimer Adler points out that there are two main opposing theories of punishment:  retribution and prevention.  As retribution, OSHA's fine would be laughable, were it not for the somber circumstances.  It is hard to imagine a retributive penalty for the West Fertilizer Company, which after all is a business firm, not an individual.  It has already been reduced to smithereens, and unless you contemplate something primitive like blowing up the houses of the owners in retribution for the explosion of their plant, it is hard to conceive of a punishment that would be purely retributive in character. 

OSHA fines appear to be based on the preventive theory of punishment, as are most administrative fines levied on corporations in general.  While it is clear that it is way too late for this fine to prevent what happened in West, it is by no means too late for other operators of fertilizer manufacturing and storage facilities to take note of the fine and the reasons why it was levied.  There are over a dozen similar fertilizer plants just in Texas alone, and it is a good bet that many of these are lacking in the same safety features that would have prevented or mitigated the accident in West.  One hopes that insurance companies will take the initiative to motivate their fertilizer-plant customers to upgrade their facilities and procedures to make it less likely that something like the West explosion will happen.  And there is always the chance that enlightened managers and owners will take it upon themselves to make the needed changes:  following existing federal guidelines about how ammonium nitrate should be stored, putting emergency procedures in place and even practicing fire drills, and taking other sensible precautions that are not rocket science but often get neglected when an organization skids by for years and avoids the very unlikely but disastrous chance that a normally well-behaved chemical like ammonium nitrate will explode. 

While it's true that the horse named the West fertilizer explosion has long since left the barn, there are many other horses of a similar nature who can be kept in place if fertilizer plants and facilities across the country learn from the sad experience of the Texas town that got famous for a reason nobody wanted.  I hope that OSHA's actions, however tardy, serve as a warning to prevent another tragedy like the one we saw last spring.

When Scientists Aren't Scientists


I recently attended a scientific conference in the Northeast U. S. (I will be purposely vague about the exact venue for reasons that will shortly become clear), and on the plane I read an article by the Harvard political scientist Harvey Mansfield that pointed out an ironic fact about science:  in order to do good science, scientists must act at least some of the time like non-scientists.  Right after that, I got to see a good example of what he was talking about.

One of the main things that attract certain personalities to science and engineering is the supposed objectivity and emotion-free quality of science.  Mr. Spock, the famously non-emotional Vulcan of the Star Trek TV series, supposedly had a temperament ideally suited for science, because emotion was never supposed to influence his judgment.  Many scientific journals insist that papers submitted to them be written in the passive voice (not "We found that. . . " but "It was found that. . . "), thus removing any trace of the author's personality from the paper and making it sound more objective.  But Mansfield pointed out that thumos (a Greek word meaning "spiritedness" or "passion") often takes over when scientists perceive a threat to something they hold dear, even if the threat comes with scientific credentials.  And many scientists who discover something that goes against the current consensus of scientific opinion have to defend their new ideas passionately against equally vigorous and emotional opposition.  In getting emotional, scientists end up acting like ordinary non-scientists, but most good scientists tend to have a certain amount of thumos that motivates them to do the hard work and defending of their ideas that are needed to get a hearing in the competitive world of research.

The night after I arrived at the conference, the sponsoring organization held a banquet which included a buffet dinner, awards, and a three-piece classical music group that could barely be heard above the conversational din in the large hall.  During dessert, the chairman got up at the raised podium and announced the name of the after-dinner speaker:  William Happer, a well-known physicist.  I had heard his name before, and as he began his talk, I remembered where:  as author of an article entitled "The Truth About Greenhouse Gases."

By now, the most famous (but by no means the only) greenhouse gas is carbon dioxide, CO2.  The conventional wisdom among most scientists, policymakers in many countries, and the general public is that (a) humanity is playing Russian roulette with the world's climate by burning so much fossil fuel, which (b) invariably makes CO2, which (c) traps heat and raises average global temperatures, which will (d) lead to all kinds of disasters, from dying polar bears to flooded South Sea islands and perhaps even an epidemic of kidney stones.  Therefore, all right-thinking citizens should be aware of their carbon footprints and do everything humanly possible to minimize them, or else go around feeling guilty for not doing so.

Prof. Happer's specialty is the way atoms and molecules absorb and emit radiation, and in the technically sophisticated and convincing talk he gave, he showed that the correlation between rising CO2 levels and global average temperature is more alleged than real.  He also showed that the role of CO­2 in the global heat balance has been greatly exaggerated, and that there are serious flaws in the way current models treat the details of how the gas absorbs radiation to affect climate.  He closed with a quotation from playwright Henrik Ibsen: "I am in revolt against the age-old lie that the majority is always right."

The audience reaction was interesting.  They were quiet at first, but when it became clear that Happer was arguing against the main claims of global warming, most people except for a small circle near the speaker resumed talking as though nothing special was going on.  There was scattered applause at the end, and then Happer asked for questions. 

The first two or three were queries about technical details.  Then a tall, rather formidable-looking man rose and mounted the podium.  I can't recall all his words, but I know he began by saying his father was one of the founders of the field of cloud physics.  He charged Happer with at least two faults: cowardice, for not being willing to attend mainstream climate-change meetings to present his arguments; and ill will, for insulting the intelligence of the climate-change community.  In response, Happer pointed at one of the charts in his presentation and said, "The facts are there."  His accuser said something else in a tone of voice that I would characterize as non-scientific, and for a moment there I wondered if the after-dinner entertainment was going to be an amateur prizefight.  Then the chairman hastily grabbed the microphone and asked the musical trio to start playing.  The audience laughed that nervous kind of laugh that means people are relieved that something really awful isn't going to happen after all, and that was the end of that.

Only it wasn't, really.  What if Happer is right, and the vast majority of climate scientists, government leaders, and the public (which is not qualified to judge) has turned a molehill of a problem into a mountain that threatens whole economies and spreads fear and misplaced priorities worldwide?  A lot of people will end up looking pretty foolish, for one thing, which is why Son of Cloud Physicist got up and said what he said.  Of course, one should not make the opposite error of thinking that every crank and holder of a fringe opinion who comes along must be right and the mainstream is always wrong.  But Happer's evidence is not the only reason to suspect that the conventional climate-change picture at least has serious flaws.  Others such as David Rutledge at Caltech have questioned the conventional wisdom as well, but for different reasons. 

Climate change happens so slowly compared to the potential progress of science that I suspect the story will be gradually rewritten as time goes on to prove the dominant powers right whatever actually happens, and it will take a clever historian to tell the real story a century or two hence.  In the meantime, those of us who have more important things to worry about than how many centimeters per year the ocean is rising can take some comfort in the chance that William Happer's voice may be heard, and scientists will act a little more like scientists in the matter of examining the technical evidence for global warming.

Sources:  Prof. Happer's excellent article "The Truth About Greenhouse Gases," written for a non-technical audience, appeared in the June/July 2011 issue of the journal First Things, pp. 33-38.  On Jan. 3, 2010, I blogged on Prof. David Rutledge's contention that we are not going ever going to burn enough fossil fuels to make much of a difference in the climate one way or another.

The Mythological STEM Crisis


What I'm about to write is considered rank heresy in some circles.  But at least one prominent expert has taken a similar position, and he has backed it up with extensive research.  So here goes.

If you have spent any time in engineering education, either as a student or instructor, you have probably heard about the alleged "STEM crisis."  STEM stands for science, technology, engineering, and math, and is the umbrella acronym for a range of academic subjects that (a) are obviously essential to the continuation of modern life as we know it and (b) are not mastered by enough students each year to ensure such continuation, at least in the U. S.  That is the story, anyway:  that we are teetering on the edge of a disaster in which our economy will crash and our technology will stagnate for lack of enough young people able to do science, technology, engineering, and math.

In a recent issue of IEEE Spectrum, a publication of the world's largest professional organization for engineers, author Robert Charette took issue with this claim, which he calls a "myth."  Why a myth?

A myth isn't a lie, exactly.  It's a story that may have elements of truth in it, but isn't necessarily wholly and literally true.  Nevertheless, there is usually a group of people who have a strong reason to believe in the myth, and repeat it over and over until belief in the myth spreads among the general population.  

Charette finds that, depending on your definition of what a STEM education or a STEM job is exactly, that many people holding STEM jobs do not have a bachelor's degree in STEM, or necessarily a college degree at all.  On the other hand, if you look at the pool of all graduates of STEM programs, most of them are currently working in fields other than STEM ones.  So it doesn't look like you necessarily need a STEM degree to get a STEM job.  And if you do get a STEM degree, unless you're lucky you are liable to end up in a non-STEM job anyway.

Anecdotes aren't statistics, but they make situations seem more real.  A student of mine graduated from my university a few years ago with a bachelor's degree in manufacturing engineering.  After an unsuccessful spring and summer looking for a technical job, he returned to school, attended another couple of years or so, and obtained his second B. S. degree, this time in electrical engineering.  Even with two STEM B. S. degrees, it took him over a year of looking before he finally found an engineering job last summer. 

If the STEM crisis was as severe as some would have us believe, people like my student would be snapped up before they graduate.  And average starting salaries in engineering would show a steady increase above average wages for as long as the crisis endured.  Neither of these things is the case, however. 

While some engineering students get jobs before they graduate with B. S. degrees, others, like the student I mentioned, have a lot of trouble finding suitable work.  And Charette notes that while average wages of STEM employees have risen faster than those of non-STEM employees over the last 30 years, the increase is not evenly distributed across all fields.  Engineers, it turns out, saw their wages rise slower than those of non-STEM workers. 

Charette suspects, and I agree, that the real reason the myth of a STEM shortage won't go away, is that it is in the best interests of those who employ STEM workers to have an oversupply from which to select the top echelon of graduates, while being able to let them go when business slows without concern that there will be a problem in rehiring when things turn for the better again.  Because the long-term employment model is now long gone, engineers can look forward to a series of short-term jobs with multiple employers anyway, and often the only way to get a raise in such an environment is to quit and join a different firm.  But as an employee, you always take the risk that you'll quit at the wrong time and be out of work for an unknown length of time. 

If the STEM crisis isn't all it's cracked up to be, does this mean that it is perverse and wrong to encourage more students to study STEM subjects?  Not necessarily.  For a variety of cultural and political reasons, K-12 education in the U. S. has fallen on hard times, and one way to help fix it is to encourage a renewed focus on STEM subjects.  There is little actual harm in running pre-engineering programs in high schools, and maybe some good results, although the longitudinal studies to prove whether such programs are really effective are so expensive that they are almost never done.  And other things being equal, providing more resources for students to study STEM subjects in college is a good thing too.  But overall, we might be better off leaving the system to adjust itself, rather than expecting that such programs will permanently put the alleged STEM crisis to rest.

As Charette points out, there is now a sizable educational and governmental establishment that is heavily invested in the STEM myth, and whose existence would be threatened if we all woke up one morning and had a good laugh at their expense by realizing that the STEM crisis is at least partly advertising rather than reality.  And turning such bureaucracies around is a political problem, not just an engineering problem.  But the first step in dealing with such problems is to realize that things aren't necessarily the way they are presented to us.

Politicians and governments can do only so much.  Most of the people I know who are truly content with their role in the engineering profession were not waylaid into it by a government-sponsored program.  Someone close to them, a relative or friend, got them interested in engineering, or perhaps they just discovered on their own that it is fun and (usually) remunerative to make things.  As long as a society allows enough freedom for people to choose their direction in life, and provides enough resources to educate those who can succeed in mastering the technicalities of engineering, there will be enough engineers to go around.  Maybe not as many as companies always want, but enough.  And the next time you read something about the STEM crisis, take what you read with a grain of salt.

Engineers and Technological Unemployment: What Are People For?

 
The ways that people make a living today are very different from what they were a generation ago.  In 1970, Detroit was still a bustling manufacturing metropolis, thousands of women earned a decent living as telephone operators, and many newspapers provided employment to linotype operators who spent their days at the keyboard of a clunky pile of machinery that molded molten type metal into sticks.  Needless to say, you will have problems finding a manufacturing job in Detroit these days, and the other jobs are history too.  Furthermore, engineers played an essential role in these changes, and leading the charge are those engineers who made computers and information technology the chief engine of creative destruction over the last few decades. 

And we are by no means done, according to a report by some Oxford researchers that was mentioned in the online magazine Salon.com recently.  Carl B. Frey and Michael A. Osborne studied the U. S. employment picture and used sophisticated (and undoubtedly computerized) data-grinding methods to discover that almost half of current U. S. jobs could eventually vanish as they are taken over by "computerisation."

Some parts of this forecast are easy to believe.  If experiments by Google and others succeed in replacing human car and truck drivers with robot drivers, long-distance truckers, bus drivers, taxi drivers, and anybody else who gets paid to drive something somewhere will have to find something else to do.  Among the ranks of engineers themselves, this sort of thing has been going on for decades too.  If you look at old photographs of the offices of large engineering firms in the 1970s, one of the most typical images is that of a huge open room filled with row after row of drawing boards, each one with its white-shirted male engineer.  The output of a roomful of engineers at drawing boards can be matched today by one modern engineer armed with CAD (computer-aided design) software.  The processes are so different that they are not directly comparable, but obviously, today's engineers have very different skills than the engineers of 1970, many of whom were little more than glorified draftsmen.  But is all this real cause for concern?  Or are we looking at the problem from too narrow an angle?

What so often goes completely unmentioned in discussions of technological unemployment, is the question of anthropology:  what is your model of the human being?  I think the model that most secular economists and researchers use is something like this.  All life is basically economic in character, and the ultimate good in this life is a smoothly functioning economy, wherein everyone capable of contributing to it works to the best of their ability and receives in turn the material benefits of their work.  That is a nice picture as far as it goes, but as a philosophy of life it's somewhat lacking.

For a completely different take on technological unemployment, you should read one of a number of works that were popular in the 1930s.  Even in the teeth of the Great Depression, writers such as C. C. Furnas in The Next Hundred Years went into optimistic technophilic raptures about how the increasing efficiency and productivity brought about by technological advances would let most people earn all the money they needed by working only one or two hours a day, leaving the rest of the time for leisure pursuits such as art appreciation and charitable work.  We have certainly gone beyond Mr. Furnas's wildest dreams of increased productivity.  So what went wrong with his vision?

I'm not entirely sure, but one factor seems to be the social consensus of what kinds of work and lives are to be desired, and what kinds are to be disparaged.  A short list of the occupations that are admired and envied in the U. S. today might start out like this:  movie stars, rock stars, the wealthy (regardless of how they made their money), sports figures, politicians (a few, anyway), . . . and it's going to be a short list because for the most part, we don't have true heroes anymore, just people who are famous for a bit and then fall victim to that favorite journalistic enterprise, The Mighty Brought Low. 

An even more important reason for the problem that most people seem dissatisfied with their occupational lot in life is that respect for ordinary, non-intellectual, perennial jobs that are nonetheless useful to society has largely vanished from the scene.  This disrespect can do tremendous psychological damage to those who hold such jobs, which in any economy is going to be the majority of workers.  Take janitors, for instance. Janitorial work is the classic job today that "don't get no respect," in Rodney Daingerfield's phrase. But it was not always thus.

My first job, outside of being paid by family friends, was sweeping the floor in a sign plant in Fort Worth, Texas.  It took me just about all day to work my way around the band saws, the bending brakes, and the vacuum molding machine.  There was no air conditioning, no breaks except for lunch, and by the time five o'clock rolled around I was ready to go home and flop—no heavy reading for this boy that summer.  But I was grateful for the work and the pay, and did it as well as I could. 

An amazing thing happened my last day on the job.  They gave me a going-away party, complete with a little cake.  I can still see their faces:  the grizzled old shop foreman who showed me the ropes my first day on the job, the skinny bandsaw operator with slicked-back black hair who always talked about how he'd rather be fishing, the red-headed cowboy who I saw one day taking liberties with the secretary (it bothered me until I found out they were married)—they thought enough of my humble sweeping up after them, to honor me and wish me well in the future. 

They did this, not because I had proved to be in the 99th percentile of floor sweepers nationwide, but because I had done a simple job with a reasonable amount of dedication.  They saw even such humble work as worthy of honor, and decided to honor me because I had done it well. 

If that deep respect for those who do any kind of honest work, technological or otherwise, were embedded in the ethos and psyche of this nation, the employment picture would largely take care of itself.  But those in charge of the economy would first have to believe in the honor of work, and then put their money where their hearts are.  And by and large, neither the money nor the hearts are in the right place today.

Cars, Cameras, and Computers: License Plates for the 21st Century


Soon after we moved from Texas to Massachusetts in 1983, I went to the Registry of Motor Vehicles (which we always referred to thereafter as the Registry of Woes, but that's another story) and got Massachusetts license plates.  Ours had some fairly typical arrangement of letters and numbers (e. g. HGQ 796), but as we spent more time there, I began to notice that a few cars had plates with only three digits, or maybe two:  "967" or "76."  It took some asking around to discover what was so special about those plates, but eventually I found out.

Turns out that those two- and three-digit plates were handed down from generation to generation, possibly even bequeathed in wills.  You see, Massachusetts was the first state in the nation to issue license plates, in 1903, and the first plates did have only two or three digits.  Somewhere along the line, the bluebloods who owned the first cars with license plates decided that some visible trace of this distinction should be left to their descendants.  So they evidently spoke with their buddies in the legislature to allow these old plate numbers to be passed to younger relatives.  So eighty years later, any latecomers to Massachusetts (and never mind if you moved there as a three-month-old, that makes you a latecomer) could look around and tell which drivers were descended from families old enough, and presumably rich enough, to have owned one of the first cars in the Commonwealth. 

I don't know if this curious habit continues there today, but if it does, it looks like Massachusetts may have to figure out a way to tell computers about the achievements of remote ancestors as well as people.  There is a good chance that everyone's license plate in the near future will have not only visible characters, readable easily by humans and with some difficulty by machines, but will also bear an invisible barcode that is much easier to read by machine than the visible characters are. 

Most people know that computers can read license-plate numbers by now almost as well as people can.  These devices, known as Automated License Plate Readers (ALPR for short) use a digital camera and a series of algorithms to separate the alphanumeric characters from the background, which task is increasingly challenging these days when custom plates have pictures of everything from blue whales to your favorite grandchild.  Once that's done, the algorithms interpret the characters and send the result to law-enforcement officials or whoever is interested.  These ALPR devices are used in automated tollbooths on toll roads, as well as their more controversial use in camera-equipped traffic signals that generate tickets for people who run red lights. 

But ALPR does not read the plates correctly 100% of the time, and so 3M and other firms have developed a type of infrared-readable ink that can be used to print a certain form of bar code directly over the visible image on the plate.  3M claims that the invisible barcode is much more reliably read by automatic bar-code readers than the visible characters, and at least one state (Virginia) is seriously considering adopting the machine-readable barcodes.  I have heard a rumor (which was the inspiration of this blog, incidentally) that many if not most states already use them, but I have not been able to confirm this rumor.  It may be the sort of thing that some states would prefer not to be known, anyway. 

We Americans are very attached to our cars, partly because the automobile is perhaps the single most significant technology that enables millions to live more independent lives in many senses.  The mobility permitted by the automobile has altered much of the country's built environment and contributes to the sense of freedom symbolized in movies when a solitary car speeds away from the camera down a lonely desert road. 

Anything that compromises the privacy of the very private space represented by the automobile tends to get our attention.  Many new cars now carry in their onboard computers a system that amounts to a "black box" which records data on control settings, acceleration, and other information that is of interest to insurance companies and lawyers in the event of an accident involving the vehicle.  And now that many cars come with GPS and wireless transceivers, not to mention the cellphones people carry, it is no long stretch of the imagination to picture a Big-Brother government knowing exactly which checkpoints you passed when, any time it wants.  The technology is already largely in place.

But in a way, the invisible-ink barcode idea is only applying to automobiles what we have already applied to our persons.  We are long since used to carrying forms of personal identification that are designed to be read by both humans and machines.  The magnetic strips on your credit cards, the RFID chips in your driver license (that's the way Texas refers to it, not as a "driver's license") and possibly a company or university ID card, and the cellphone in your pocket that is kept track of by your phone company are earlier steps in this direction.  There has been a lot of speculation (including an article that I contributed to in a professional magazine) that sooner or later, having some sort of RFID chip permanently implanted in your body will either become popular as a voluntary form of self-imposed cyborgism, or will be required by the state at some point.

Compared to having an RFID chip implanted on your person, letting your state's motor vehicle office put invisible ink on your license plate is not that big a deal.  From a technical point of view, it's just an incremental improvement that will simplify and improve the accuracy of machines that read license plates.  But the very fact that someone thought it interesting enough to spread a rumor about it says that invisible ink on license plates may cross another invisible line on the way to a future that not all of us would like to see happen.

Wisdom Literature for 21st-century Engineers


The other day I received a copy of a book written by a retired engineering professor and academic administrator named Lyle Feisel.  Prof. Feisel has found plenty of good works to do in his retirement, one of which was to write a column for The Bent, the magazine of the Tau Beta Pi engineering honor society.  He has collected these columns in a book with the title Lyle's Laws:  Reflections on Ethics, Engineering, and Everything Else. University administrators as a group are not noted for their literary brilliance or scintillating wit, and I will admit I opened the book with some trepidation.  But even after I had read (and enjoyed) it, it took me a while to figure out what category of literature it was. 

It's not an ethics textbook, by any means.  There are no homework problems, and each of its forty or so chapters is only a few pages long, dealing with a separate topic introduced by the "law" in question:  a single word or phrase followed by a brief aphorism.  Even though the chapters are independent, a particular view of the world emerges from the whole as you read.  That doesn't mean it's a work of philosophy, either—Prof. Feisel uses no fancy philosophical vocabulary, and makes no pretense of adhering to any particular philosophical or religious system. 

Finally it struck me what the book was:  it's a work of wisdom literature for 21st-century engineers. 

Wisdom literature is what scholars call the literary genre represented by the books of Proverbs and Ecclesiastes in the Hebrew Bible.  These books are collections of short, informal words of advice, without much in the way of overall organization or pattern, but rich with anecdotes, stories with a moral, and observations on human nature.  So is Lyle's Laws. 

Wisdom is not a word that gets a lot of use these days.  I once heard it defined as the ability to apply knowledge effectively, and that covers not only what engineers should do but what anyone with specialized knowledge has an obligation to do.  Many, if not most, of Lyle's Laws are not original.  For instance, No. 25, "Possibility:  If it can happen, it will happen" derives from that principle known to all working engineers, Murphy's Law ("If anything can go wrong, it will.").  But Feisel's form of the law allows for unexpected good things to happen as well, though you shouldn't count on them happening as a part of your design!  I heard a version of another law—"Discoverability:  Don't record anything you don't want the whole world to see"—from an older engineering professor in the 1990s, who told me he always warned his students not to write down anything that you wouldn't mind seeing reprinted on the front page of the New York Times.  But that's what wisdom consists of:  basic truths about human nature and human relations that are often learned by experience and passed on from generation to generation.  As C. S. Lewis pointed out in The Abolition of Man, it's as hard to devise a truly original moral principle as it is to come up with a new primary color besides red, blue, and green. 

But if there is moral medicine in Lyle's Laws, it is covered with a pleasant and engaging outer coating of war stories (some of them literally that:  the author is a Navy veteran), professional and personal tales that introduce many of the chapters, and a tone that is never preachy or didactic.  Sometimes you read a book and wish you could meet the author afterwards, and this is that kind of a book. 

This is true despite the fact that I found myself mentally squirming after reading a few of the chapters, notably the one entitled "Comfort:  Beware the cozy comfort zone."  Somewhere in the book I came across the question, "What do you know how to do now that you didn't know how to do a year ago?"  That prompted me to think about how much of what I do is simply more of the same, and how much is something I don't know how to do, but want to learn, even at the cost of some mental anguish and frustration.  This is an especially good question for tenured professors, who sometimes appear to the outside world to be entitled to coast for the rest of their lives.  Fortunately, I was able to come up with a few things I've learned in the past year, anyway, and I hope to add to the list as time goes on. 

Who should read this book?  I think there's a difference between who should read it and who will read it.  I would like every undergraduate engineering student in the English-speaking world to read the book (and so would Prof. Feisel, obviously).  If they did, and if they took the advice in the book to heart, they could avoid a lot of the errors, screwups, and cases of bad judgment that sometimes make the lives of young engineers as interesting as they are.  But that is a dream impossible of realization, short of some rich guy taking the notion to send free copies to all engineering schools.  I suspect that many of the people who will read the book are those of us in the late summer and fall of our careers, who can relate to the historical situations that Prof. Feisel alludes to and resonate with the truths he elucidates from his stories and experiences.  But the book would also serve as a good recommended read for engineering ethics courses, and I hope it will be used that way.

In my technical lectures, I occasionally mention a historical anecdote in connection with my technical topic of the day, and I have learned that a little of such material goes a long way.  Most young people, at least most young engineering students, are not that interested in history.  The spirit of our age is inherently forward-looking and views history as something to be overcome and surpassed, not something to learn from.  And for the most part, that is a good thing.  Too much regard for the past keeps you from moving into the future as fast as the next guy, as I have learned from my own experience.  But the human side of engineering is a function of human nature, which doesn't change.  And Lyle's Laws is one of the most easily read, and yet rewarding, works on human nature and engineering that I have come across in years.
