Regulating A.I. “Is a Recipe for Poor Laws and Even Worse Technology”

(p. A27) “Artificial intelligence” is all too frequently used as a shorthand for software that simply does what humans used to do. But replacing human activity is precisely what new technologies accomplish — spears replaced clubs, wheels replaced feet, the printing press replaced scribes, and so on. What’s new about A.I. is that this technology isn’t simply replacing human activities, external to our bodies; it’s also replacing human decision-making, inside our minds.
The challenges created by this novelty should not obscure the fact that A.I. itself is not one technology, or even one singular development. Regulating an assemblage of technology we can’t clearly define is a recipe for poor laws and even worse technology.

Musk’s Slow Hunch May Be Undone by Smaller Satellites

(p. B3) SpaceX ‘s long-delayed Falcon Heavy rocket, slated for its maiden flight on Tuesday [February 6, 2018], faces uncertain commercial prospects and lacks a clear role in efforts to send U.S. astronauts back to the moon or deeper into the solar system.
The company conceived the rocket at the beginning of the decade, when SpaceX was an underdog fighting to increase its share of launches and needed a beefed-up alternative to a fleet of underpowered boosters. But after spending some $1 billion and grappling with five years of delays and huge technical challenges related to reliably harnessing power from 27 engines, the company is contending with significantly eroded commercial demand for such a potent heavy-lift booster.
The primary reason for the weakened demand is that both national security and corporate satellites continue to get smaller and lighter. So now, even if it performs as advertised, the Falcon Heavy might be Elon Musk’s biggest contrarian bet since he founded SpaceX over 15 years ago.

Level of Loneliness About the Same as 70 Years Ago

(p. 8) . . . is loneliness, as many political officials and pundits are warning, a growing “health epidemic”?
. . .
The main evidence for rising isolation comes from a widely reported sociology journal article claiming that in 2004, one in four Americans had no one in their life they felt they could confide in, compared with one in 10 during the 1980s. But that study turned out to be based on faulty data, and other research shows that the portion of Americans without a confidant is about the same as it has long been. Although one of the authors has distanced himself from the paper (saying, “I no longer think it’s reliable”), scholars, journalists and policymakers continue to cite it.
The other data on loneliness are complicated and often contradictory, in part because there are so many different ways of measuring the phenomenon. But it’s clear that the loneliness statistics cited by those who say we have an epidemic are outliers. For example, one set of statistics comes from a study that counted as lonely people who said they felt “left out” or “isolated,” or “lacked companionship” — even just “some of the time.” That’s an exceedingly low bar, and surely not one we’d want doctors or policymakers to use in their work.
One reason we need to be careful about how we measure and respond to loneliness is that, as the University of Chicago psychologist John Cacioppo argues, an occasional and transitory feeling of loneliness can be healthy and productive. It’s a biological signal to ourselves that we need to build stronger social bonds.
Professor Cacioppo has spent much of his career documenting the dangers of loneliness. But it’s notable that he relies on more measured statistics in his own scientific papers than the statistics described above. One of his articles, from last year, reports that around 19 percent of older Americans said they had felt lonely for much of the week before they were surveyed, and that in Britain about 6 percent of adults said they felt lonely all or most of the time. Those are worrisome numbers, but they are quite similar to the numbers reported in Britain in 1948, when about 8 percent of older adults said they often or always felt lonely, and to those in previous American studies as well.

Mars Is Humanity’s “Backup Plan”

(p. C3) The stated goal of the U.S. Mars program is to create a permanent base there. That is difficult to imagine in the planet’s harsh environment, which was depicted with such stark realism in the 2015 film “The Martian.”
But there are possibilities on the planet for making bases more viable. Mars explorers could use natural lava tubes in extinct volcanoes to create an underground base shielded against harmful radiation. Underground deposits of ice discovered in recent years could be used for drinking water and to provide oxygen for breathing, as well as hydrogen for rocket fuel. In theory, astronauts could eventually establish agricultural stations to create a self-sustaining colony, using genetically modified plants that could thrive in a cold environment rich in carbon dioxide.
A new spirit of exploration and discovery is certainly part of the push for this new space age, but concerns about the future of the Earth are also a motive. There is a growing realization that life on the planet is extremely fragile, that killer asteroids, super volcanoes and ice ages have nearly extinguished life in the past, and that climate change may spin out of control. Even if the Earth remains habitable, we know that one day the sun itself will expire.
So the choice ultimately will be simple: Colonize outer space, or perish. We need an insurance policy, a backup plan. The dinosaurs didn’t have a space program. We may need ours to evade their fate.

Extent of Future Global Warming Remains “Stubbornly Uncertain”

(p. A15) . . . , an exemplary French report . . . begins, “But uncertainty about how hot things will get also stems from the inability of scientists to nail down a very simple question: By how much will Earth’s average surface temperature go up if the amount of CO2 in the atmosphere is doubled?”
“That ‘known unknown’ is called equilibrium climate sensitivity (ECS), and for the last 25 years the U.N.’s Intergovernmental Panel on Climate Change (IPCC)–the ultimate authority on climate science–has settled on a range of 1.5 C to 4.5 C.”
The French report describes a new study by climate physicists Peter Cox and Mark Williamson of the University of Exeter and Chris Huntingford of the U.K.’s Center for Ecology and Hydrology. Not only does it narrow the range of expected warming to between 2.2 and 3.4 degrees Celsius, but it rules out the possibility of worrying outcomes higher than 4 degrees.
. . .
. . . , [the IPCC] backpedaled in 2013 to adopt a wider range of uncertainty, and did so entirely in the direction of less warming.
. . .
The IPCC’s new estimate was no more useful or precise than one developed in 1979 by the U.S. National Research Council, when computers and data sets were far more primitive.
This 40-year lack of progress is no less embarrassing for being thoroughly unreported in the mainstream press. The journal Nature, where the new study appears, frankly refers to an “intractable problem.” In an accompanying commentary, a climate scientist says the issue remains “stubbornly uncertain.”

Blobel Pursued a Slow Hunch for Over 30 Years

(p. B19) Günter Blobel, a molecular biologist who was awarded the 1999 Nobel Prize in Medicine for discovering that proteins in any living cell have virtual ZIP codes that guide them to where they can help regulate body tissues, organs and chemistry, died on Sunday [February 18, 2018] in Manhattan. He was 81.
. . .
The cause was cancer.
. . .
He spent nearly all his working life at Rockefeller University, what he regarded as the Valhalla of research.
Like many scientific advances, Dr. Blobel’s had no moment of “Eureka!” It unfolded over 30 years of painstaking, often frustrating, but occasionally thrilling investigation: a process of building on others’ work, intuitive thinking to form new hypotheses, and testing, using the results to modify his theories, and then testing and modifying again and again.
Driven to find underlying causes of diseases that were being treated for symptoms, and funded by the National Institutes of Health and the Howard Hughes Medical Institute, he successively developed five models of his original “beautiful idea.” Along the way he won many prestigious awards, some for essentially the same insights recognized later by the Nobel committee.

Free Trade Increases Economic Growth

(p. 3) When President Trump imposed tariffs on imported solar panels and washing machines, I was reminded of a line from George Orwell: “We have now sunk to a depth at which the restatement of the obvious is the first duty of intelligent men.”
. . . , my subject is economics, and to most people in my field, the benefits of an unfettered system of world trade are obvious.
. . .
. . . , economists have emphasized how trade affects productivity. In a model pioneered by my Harvard colleague Marc Melitz, when a nation opens up to international trade, the most productive firms expand their markets, while the least productive are forced out by increased competition. As resources move from the least to the most productive firms, overall productivity rises.
. . .
A skeptic might say that all this is just theory. Where’s the evidence?
One approach to answering this question is to examine whether countries that are open to trade enjoy greater prosperity. In a 1995 paper, the economists Jeffrey D. Sachs and Andrew Warner studied a large sample of nations and found that open economies grew significantly faster than closed ones.
. . .
Trade restrictions often accompany other government policies that interfere with markets. Perhaps these other policies, rather than trade restrictions, impede growth.
To address this problem, a third approach to measuring the effects of trade, proposed by the economists Jeffrey A. Frankel of Harvard and David C. Romer of the University of California, Berkeley, focuses on geography. Some countries trade less because of geographic disadvantages.
For example, New Zealand is disadvantaged compared with Belgium because it is farther from other populous countries. Similarly, landlocked nations are disadvantaged compared with nations with their own seaports. Because these geographic characteristics are correlated with trade, but arguably uncorrelated with other determinants of prosperity, they can be used to separate the impact of trade on national income from other confounding factors.
After analyzing the data, Mr. Frankel and Mr. Romer concluded that “a rise of one percentage point in the ratio of trade to G.D.P. increases income per person by at least one-half percent.”

Politicians Build Costly Megaprojects to Burnish Their Legacy

(p. 14) Petroski, a professor of both engineering and history at Duke and the author of such books as “The Pencil” and “The Evolution of Useful Things,” brings an eye for the little things: what kinds of guardrails are best, how roads can be made safer through better signage, which paving materials last longest. One of his key lessons is that small thinking can be a virtue, because the history of infrastructure is a series of experimental and incremental improvements.
Local governments tried endless variations of asphalt and concrete before developing paving surfaces that didn’t produce excess dust or deteriorate quickly under rain and snow. They gradually built longer bridges, learning from earlier designs that worked, and that didn’t. They tried out different paint colors for lane markings, finding the ones that drivers could see best.
This little-things perspective is needed at a time when America’s infrastructure agenda is simultaneously characterized by grandiose ambitions and limited budgets. Money is tight, and infrastructure needs are going unaddressed. At the same time, despite funding limitations, politicians have a tendency to fall in love with novel, pathbreaking, expensive projects that frequently go astray, resulting in arguments against spending more on infrastructure.
. . .
Politicians aren’t drawn to megaprojects just because they believe the initial rosy cost projections and therefore underestimate the risk of complications. They also see an opportunity to build their legacy: It’s more fun to say “I built that bridge” than “I retrofitted that bridge.”

The Only Duty of a Firm “Is to Produce Profits”

(p. B1) On Tuesday [January 16, 2018], the chief executives of the world’s largest public companies will be receiving a letter from one of the most influential investors in the world. And what it says is likely to cause a firestorm in the corner offices of companies everywhere and a debate over social responsibility that stretches from Wall Street to Washington.
Laurence D. Fink, founder and chief executive of the investment firm BlackRock, is going to inform business leaders that their companies need to do more than make profits — they need to contribute to society as well if they want to receive the support of BlackRock.
. . .
(p. B3) Companies often talk about contributing to society — sometimes breathlessly — but it is typically written off as a marketing gimmick aimed at raising profits or appeasing regulators.
Mr. Fink’s declaration is different because his constituency in this case is the business community itself. It pits him, to some degree, against many of the companies that he’s invested in, which hold the view that their only duty is to produce profits for their shareholders, an argument long espoused by economists like Milton Friedman.
“What does it mean to say that ‘business’ has responsibilities? Only people can have responsibilities,” Friedman wrote, almost rhetorically, back in 1970 in this very newspaper. “Businessmen who talk this way are unwitting puppets of the intellectual forces that have been undermining the basis of a free society these past decades.”

Russian Movie Director Bravely Criticizes Putin

(p. A8) MOSCOW — While shooting “Loveless,” an Oscar nominee this year for best foreign film, Andrey Zvyagintsev repeated virtually every scene again and again — 12 takes on average, according to his cinematographer, sometimes as many as 28.
The differences between takes often proved undetectable to others, said the cinematographer, Mikhail Krichman — even to the core crew that has worked on all five of his films. But the director sought some fleeting “magic.”
It might be several leaves fluttering off a tree in the background, Mr. Krichman said, or the angle at which snowflakes struck a window. “These kinds of things deliver the magic of the scene, and he uses them to decide to take it or not for the movie,” Mr. Krichman said of Mr. Zvyagintsev. “That makes him very different from other directors.”
. . .
His role as social critic, . . . , is another reason the art-house crowd tends to respect Mr. Zvyagintsev. He is one of the few high-profile artists still brave enough to openly criticize the Russian government.
He has disparaged the recent crackdown on the arts, including the house arrest of a prominent theater director and the use of censorship for the first time in years to ban a foreign movie, “The Death of Stalin.”
“We believed that in 1991 that we were present for the burial of the C.P.S.U.,” he said referring to the one-party state of the Soviet Union. “The burial did not take place. Instead, the corpse rose from the coffin and is walking around and frightening us once again.”
