"Trumpism on steroids"

Brookings has released a new thought-provoking piece on the economic and political consequences of automation. Among other sources, it quotes an Oxford University study that 47% of U.S. workers have a high probability of seeing their jobs automated over the next 20 years. The Brookings authors go on to say:
While some dispute the dire predictions on grounds new positions will be created to offset the job losses, the fact that all these major studies report significant workforce disruptions should be taken seriously. If the employment impact falls at the 38 percent mean of these forecasts, Western democracies likely could resort to authoritarianism as happened in some countries during the Great Depression of the 1930s in order to keep their restive populations in check. If that happened, wealthy elites would require armed guards, security details, and gated communities to protect themselves, as is the case in poor countries today with high income inequality. The United States would look like Syria or Iraq, with armed bands of young men with few employment prospects other than war, violence, or theft.
Wow. And you thought global warming was scary. It is, but so is this.

Wait, there's more:

With some workforce disruption virtually guaranteed by trends already underway, it is safe to predict American politics will be chaotic and turbulent during the coming decades. As innovation accelerates and public anxiety intensifies, right-wing and left-wing populists will jockey for voter support. Government control could gyrate between very conservative and very liberal leaders as each side blames a different set of scapegoats for economic outcomes voters don’t like. The calm and predictable politics of the post-World War II era likely will become a distant memory as the American system moves toward Trumpism on steroids (emphasis added).
I've written before that the election of Donald Trump was a confluence of several trends in America, one of which was a subset of the electorate justifiably angry about a lack of economic opportunities for themselves and their children — particularly outside the growing, affluent urban areas. Conventional wisdom says the U.S. doesn't manufacture much of anything anymore, but the statistics say the opposite: manufacturing in the U.S. is at an all-time high, in terms of dollar output. However, manufacturing employment remains low because technology allows more goods to be manufactured without more workers.

Increased productivity, as defined by economists, was supposed to be a good thing. And for people with IT or engineering skills who set up and maintain these highly automated factories, it is a golden age. But not everybody has an IT or engineering background, and even if everyone did, the number of jobs in those fields is finite.

Brookings describes a startling future when Americans become so disenchanted with low-wage employment in service jobs that serious political consequences ensue. I believe we've already seen the start of it. New import tariffs and threats of a trade war with China are political reactions to the distress of these Americans. Such tactics aren't likely to achieve anything positive and could actually make things worse. But if dystopia is to be averted, we need action of some type… better ideas and the will to implement them. Otherwise, the Brookings piece has an attribute of inevitability.

Picking a coach

More than three months after Alabama beat Georgia for the NCAA football championship, I love watching replays of The Pass. Gail once paraphrased, "You can take the boy out of Alabama, but you can't take..." In some ways I suppose she's right.

My in-laws in Georgia will have to indulge me. Watch it here, which offers eight different views. But the last of those views — ESPN's Coaches Film Room — is what I write about today.

Six NCAA coaches were on the air live, although the view of one was obscured. This screen capture was taken as the play developed:


And after the play was over:


If I were a high school football star about to decide which university to play for and all the offers were equal, the second photo tells me all I'd need to know. The guy with the smile is Pat Fitzgerald of Northwestern. He's a former linebacker, a two-time consensus All-American. I'll bet he is tough as nails during practice. But for heaven's sake, give me a coach who enjoys the game and isn't afraid to show it.

And he wins, too.

What electrical engineers do

Yesterday Peter Grünberg died in Germany at 78. Never heard of him? Relax, hardly anyone outside the physics community had, despite his Nobel Prize. The discovery of giant magnetoresistance (GMR) is just what the New York Times said: a unique enabling technology for many popular consumer devices such as the Apple iPod.

After the physicists had developed the theory of GMR, built a prototype, and published the results, the electrical engineers took over. The approximate sequence of events:

  • The physical size of the prototype had to be reduced from several inches to about 1 millimeter.
  • The component had to be designed for resistance to shock and temperature (within reasonable limits) and to have an in-service failure rate of something like 1 failure per year per 10,000 devices.
  • The component had to be connectable to other components.
  • A manufacturing line had to be set up that could make millions of the components per year, at a unit cost of a dollar or so, with less than 1 manufacturing defect per 100,000 units.
  • And then the component had to be designed into a device like an iPod that consumers would buy by the millions, with a price and a cost that would make a profit for Apple.
Physicists (and mathematicians) and electrical engineers have complementary skills. Each knows something about the other, but each brings its own perspective. Physicists and mathematicians seek truth and beauty. Engineers seek practicality. As someone told me once, the definition of an engineer is he or she who can build for $10 a device that would take everybody else $100.

And there's another key difference: Grünberg and his French colleague Albert Fert were assisted by graduate students, no doubt, but the discovery of GMR is principally theirs. However, hundreds if not thousands of electrical engineers — almost all anonymous, outside their own employers — were needed to put GMR to work. And in the process, most of these engineers were organized into separate teams, each with its own specialty or assignment in the work breakdown structure.

During my undergrad years at Georgia Tech, I had to pass 8 electrical engineering lab courses. Three of us took all our labs together. The first guy was responsible for reading the lab assignment each week and prepping us for the steps to take. The second guy was responsible for collecting data during the lab and ensuring that the numbers made sense before we left. I was responsible for writing and submitting the report on time and answering any questions from the TA. This worked like a charm; each of us was good at our role on the team.

I hear that undergrad EE labs are no longer designed to force teamwork, and that's a pity. Teamwork is so important to adult success. You don’t have to be on an athletic scholarship to learn about teamwork.

Good and Bad

My comments on some contemporary events:
  • Good: Building the Atlantic pipeline into North Carolina. In an ideal world, we would be curtailing use of fossil fuels — and we should aim for that. But in today's world, I'd rather see Duke Energy burning natural gas than coal. Is there a legitimate concern about fracking? Yes, I oppose fracking because of its consumption of groundwater (which we don't have a lot of) and its uncertain long-term effects on geology. But the pipeline could just as easily carry natural gas from other sources. Yes, eastern North Carolina has a lot of poverty and the pipeline is running through mostly impoverished territory, but the proper response to that is to keep trying programs that address the woes of northeastern NC.
  • Bad: Enraged dad Randall Margraves attacks Larry Nassar in court. We know why Margraves is angry. I'd be angry too. We also know that some people have a limited capacity for self-control. But we have a system of justice, not personal vendettas or lynching. Let the police, courts, and prisons do their jobs. We cannot condone what Margraves did or tried to do.
  • Good: NCDOT is finally moving to complete NC 540 around Raleigh. Opponents say that completing 540 will increase pollution and encourage sprawl. Yes, we need mass transit and Wake County residents just voted for a sales tax to that end. But to suspend construction of highways is absurd. So is expecting the growth of the Triangle from 2 million to 4 million people over the next 30 years — yes, that's the forecast — not to expand the footprint of developed land. As for pollution, just think of how much pollution comes from cars sitting for hours in traffic that doesn't move. And our buses need better roads, too. Pave, baby, pave.
  • Bad: Sexual harassment in Hollywood. The words "casting couch" are not new, but did anyone imagine that so many female actors were being abused? I first became a manager of people in 1981, and from day one there were women reporting to me. For 35 years I have consistently worked to give women in the workplace fair treatment. Not once have I hit on a woman who reported to me or had applied for a job that I had posted. It astonishes me how many men can't keep their hands off women.
  • Good: The church that I attend has completed a $75,000 installation of solar panels. The message is that people of faith, regardless of their tradition, believe that protecting the environment is an imperative. Will it also reduce electricity expense? Of course. Do we know how much we will save? No, but ask us in a few years when we will be able to tell you. Sometimes, a bold step is required to illuminate the path for others.
  • Bad: Suspending the work rights of spouses whose partners entered the U.S. on H-1B visas. I have had misgivings about the H-1B visa program from the start. However, the people who have come to the U.S. under the program — largely from India and China — have strictly complied with the law. They are not "illegal immigrants" or even "undocumented workers". If you believe that the H-1B program should be killed, ok. I might agree with you. But don't take the coward's way out of forcing the people to go home by making it financially infeasible to stay here.
  • Good: The risks of prescription pain medications are becoming understood. Yes, oxycodone is good when you have a kidney stone. I can testify to that. Likewise if someone has terminal metastatic cancer. Aside from those situations, opoids are to be avoided. I won't say that all physicians have been irresponsible, but clearly some have been. Journalists are now illuminating how the crisis came to be. We need good journalism now more than ever.
  • Bad: GenX. Somehow, a chemical that no one understands has been allowed to enter the water in southeastern North Carolina. I am not easily frightened, but this sounds genuinely scary. Once the rivers and groundwater become polluted, it is very difficult to rid them of a noxious agent. The clear message from my chemistry classes and a summer job working in a real chemical lab was never to let your guard down when using a fluorinated organic chemical. Ever.

Irrational exuberance in Alabama

If I had a dollar for every item I've read this week about a new wave in American politics — signalled by the victory of Doug Jones in Alabama — I could afford better wine at dinner. But it just ain't so.

Jones' election was a fluke, made possible only by the horror of his opponent. If Jones had run against the more moderate (less extreme?) Luther Strange, who had been appointed by the Governor of Alabama to fill the vacancy when Jeff Sessions became Attorney General, Jones would not have won. And assuming the Republican opponent for Jones in November 2020 is no clone of Roy Moore, the Republicans are almost certain to reclaim Jones' seat. It's simple math: white folks are about 70% of registered voters in Alabama, and under normal circumstances 80% of white Alabamians vote Republican.

But circumstances this week were not normal. All of the following statements about Jones' victory are true:

  1. Jones won because black Alabamians had high turnout.
  2. Jones won because white Alabamians had low turnout.
  3. Jones won because just enough white Alabamians trashed their votes by writing in.
  4. Jones won because just enough white Alabamians — mainly women, residents of the four major cities (Birmingham, Mobile, Huntsville, and Montgomery), and residents of the university cities (Tuscaloosa and Auburn) — voted for him.
None of these four, individually, would have put Jones over the top. Some Democrats anxious to reverse their loss of the White House in 2016 are reading too much into Jones' victory. For #1, black Alabamians have had high turnout before but even then, there simply aren't enough of them to be a decisive factor in the absence of something else. For #2, #3, and #4, one can speculate about the cause but in all likelihood it was specific to Moore. General trends in Alabama voting remain unchanged.

I did read assertions that white millennials in Alabama voted Democratic. Perhaps that's true, but I've been reading for 10 years that millennials and demographics will give Democrats the edge nation-wide. It hasn't happened yet. Democrats need an answer that's better than "wait 'til next year". They need solid candidates with solid messages, delivered through solid campaign strategies and underwritten by solid finances. There are no short cuts.

Why GE failed

This morning on NPR I heard a well-written piece on the failure of General Electric to thrive. I agree with the points made by Brian Mann, but I want to add mine.

GE under the once-acclaimed Jack Welch featured two management practices. One was the ruthless elimination each year of the "bottom 10%" and the other was Six Sigma systematic quality.

No one dared speak up at the time, but the truth is that many of us believed the "annual bottom 10%" practice to be unfair, inherently political, and ultimately counterproductive. A lot of people refused to consider working for a company that practiced it. It took a while, but the inability of GE to attract creative people in large numbers is a silent factor in bringing the company to its knees.

As for Six Sigma, it's a great idea when you are manufacturing millions of units of the same product: light bulbs, smartphones (the hardware, that is), etc. The benefits of Six Sigma are indisputable in that context. However, Six Sigma does not help you innovate to bring new products to market. That takes a different set of skills and techniques, and you'll find that experts in the "front end" of the business would rather slit their wrists than work under a Six Sigma regime.

Combine these two factors, and you can understand why GE quit innovating. Instead their focus was cost-reduction and financial optimization. After 30 years GE simply ran out of costs to reduce and optimizations to implement; the company became strategically bankrupt. Meanwhile, the easy money that Welch made in the financial markets and that kept investors happy while obscuring the company's underlying problems dried up abruptly after 2008. If you play with fire, you get burned eventually.

I saw something similar happen to Nortel, my former employer, although not exactly in the same sequence. From the mid-1970s on, Nortel was the most successful company across the globe in the telecommunications products space. At one time Nortel was the tenth most valuable company in the world. But it went bankrupt in 2009. How'd that happen? You can find hundreds of explanations, but to my eyes it's simple: the company ceased to offer products that customers were willing to pay Nortel's historic margins for. Despite the heroics of its R&D team in the 1970s and 1980s, Nortel died from a lack of innovation. There were other contributing causes, not the least of which was the adoption company-wide of Six Sigma just when the crap was hitting the fan. All that Six Sigma accomplished, really, was diverting the attention of management and hundreds of the company's best employees to solve problems that just didn't matter in the big picture. When you are bleeding to death, don't obsess over small cuts on your toes.

The Welch philosophies and practices have been injected into the core of most if not all MBA curricula. I hope that B-school professors now reexamine the long-term legacy of Welch and revisit the importance of innovators — something that Steve Jobs, despite his awful personality, understood quite well.

Organic peroxides at Arkema in Houston

The Arkema chemical plant in Houston makes a variety of organic peroxides under the Luperox brand name. Any type of peroxide is worthy of careful handling — even the hydrogen peroxide you're familiar with at home. Over-the-counter sales of H2O2 at groceries and pharmacies are limited to 3-5% concentration for this reason. Concentrations of 30% or more H2O2 can be quite hazardous. Another clue to the unstable nature of peroxides is that the H2O2 you buy must be protected from light by an opaque container.

Many but not all of the Luperox organic peroxides must be kept chilled to reduce their instability. The plant is no longer able to chill them because of flooding (the same root cause as Fukushima). The organic peroxides themselves are not particularly toxic in relation to industrial organic chemicals overall. However, they produce gas as they decompose, and this gas must go somewhere. Furthermore, the process of decomposition produces heat — that is, it's exothermic — and this heat accelerates the decomposition of the organic peroxides that remain. As the heat builds up, you can conceivably reach the flash point of a decomposition product.

One of the gases produced by decomposition is pure oxygen. Any fire that arises will be fed by that oxygen. Another concern is that the products of decomposition (other than oxygen) when burned can conceivably create airborne chemicals that are toxic. This is true with almost any fire that's fed by industrial organic chemicals.
