ABOUT THOSE JOB-KILLING ROBOTS
Every day, there are articles and blog posts about how quickly robots are replacing jobs, particularly in manufacturing. These often include assertions along the lines of “robots are replacing human labor so rapidly and so completely that it doesn’t really matter whether the factories are in the US or somewhere else.” There are also many assertions that robotics and artificial intelligence will triumph so completely that we must accept that we will permanently have a huge unemployed population who will need to be paid a “basic income” of some sort from the government.
This May, there were breathless headlines about how Foxconn, which is Apple’s primary contract manufacturer, was replacing 60,000 workers with robots–indeed, in some tellings, had already replaced them. If you google “foxconn 60000 workers”, you will get about 130,000 hits.
But the story, however, is false; indeed, it did not even originate with Foxconn but rather with some local Chinese government officials who wanted to promote their area as “innovative.”
There has also been a lot of coverage of robotics at Adidas, which is trying to use automation to improve the labor productivity of shoe-making to the point that it can be done economically in high-wage countries such as Germany. This article on Adidas also cites the Foxconn “60,000 jobs” assertion.
One key pair of numbers is missing from the stories I’ve seen on the Adidas project: the ratio of human workers to shoes produced, with and without the addition of the robotics. You can’t really judge the labor-reducing impact of the project without these numbers. In this Financial Times article, Adidas is quoted as saying, entirely reasonably, that they will need to get further into production with their new factory before developing meaningful productivity numbers. The article also cites Boston Consulting Group as estimating that by “2025 advanced robots will boost productivity by as much as 30 per cent in many industries.” Thirty percent is a very significant number, but it’s a long, long way from a productivity increase that would imply that factory jobs don’t matter, or that we’re going to inevitably have a very large permanently-unemployed population.

STATISTICAL MALPRACTICE, CLUELESSNESS ABOUT HUMANS
Almost every day, I see someone arguing that we shouldn’t worry about terrorism so much because your chances of being killed by a terrorist are less than your chances of being killed in an auto accident, or by slipping in the bathtub, or some such comparison. Barack Obama, according to The Atlantic, “frequently reminds his staff that terrorism takes far fewer lives in America than handguns, car accidents, and falls in bathtubs do.”
Indeed, this argument was even being made shortly after 9/11, even being made by people with obviously high intelligence and mathematical knowledge. Marvin Minsky, MIT professor and pioneer in the field of artificial intelligence, recommended scrapping “the whole ‘homeland defense’ thing” as “cost-ineffective.” According to the WSJ, Minsky calculates that the cost of preventing each terrorist-caused airplane fatality would be around $100MM, and that “we could save a thousand times as many lives at the same cost by various simple public-health measures.” Whatever one thinks about the performance of Homeland Security as an organization, as a matter of logic Minsky’s argument was just plain wrong, as are its present-day equivalents.
Calculations of probability must be based on assumptions about whether the rate at which some phenomenon is occurring is static or is subject to change. Based on the numbers of influenza in 1914, you might have concluded that you were not at material risk of dying from this disease. In 1918, things looked very different. The dynamics of the disease led to a very rapid increase in the probability of infection.
If the FAA receives some service difficulty reports indicating that cracks have appeared in the wing spars of a few aircraft that have reached about 10,000 hours in service…aircraft of this service level representing a small portion of the total production for this model…they’re not going to dismiss it with ‘well, no biggie’ and wait until substantial numbers of planes reach 15,000 hours or so and have the wing spars actually break in flight. They’re going to analyze the situation and quite likely issue an Airworthiness Directive against the aircraft, requiring inspections and remedial action.
The wing spar case is an example of a process in which the mere passage of time can change the probabilities of the adverse event occurring. The influenza case is an example of a malign positive feedback loop, i.e., a vicious circle–the more people become infected, the more other people they infect. Positive feedback loops tend to have exponential growth patterns until something stops them.
In the case of terrorism, it should be obvious that successful terror attacks act as encouragement for future acts of terror–definitely a positive feedback loop. Remember what Osama bin Laden said about people wanting to side with the ‘strong horse’? Moreover, terror attacks are demoralizing to the target country in a way in which random accidents are not. There has already been a chilling effect on free speech driven by the desire to avoid angering the Islamists.

LOYALTY AND RISK-TAKING
My student cohort held him in awe: We’d been told that he had received an Air Medal during the war for saving a squadron mate’s life, or his liberty anyway. The latter had come off target badly hit and managed to limp only as far as the harbor at Hai Phong before his machine came apart. The pilot had been forced to eject and was floating in his raft a mile or so off shore, when he saw an NVA patrol craft bounding out to seize him. The unlucky aviator was contemplating the austere amenities of the Hanoi Hilton when our CO roared overhead at 500 feet, firing a Shrike missile in boresight mode.
The Shrike is an anti-radiation missile, designed to home on enemy radar and destroy it. The radar-following mechanism is its only guidance system; the only way to hit a target that is not emitting radar is to get very close to it before you fire the missile–thereby placing yourself at considerable additional risk Lex’s CO had taken that risk, destroying the North Vietnamese patrol craft, and making it possible for the shot-down pilot to be rescued by helicopter..
Reading the story, I couldn’t help wondering: which if any of our current crop of political candidates and leaders would–in the extremely unlikely event that they ever found themselves flying combat aircraft–have made the same decision?

AUTOMATED SYSTEMS NEED TO BE SUPERVISED BY HUMANS
…and not just any humans.
Automated systems need to be supervised by humans, and not just any humans, as Stanislav Petrov’s story makes clear. Individuals and bureaucracies that themselves behave in a totally robotic fashion cannot be adequate supervisors of the automation. See also my post Blood on the tracks for an additional example.

THE UNITED STATES OF WEIMAR?
There is much political violence in the US these days, ranging from attacks on Trump rally attendees to protesters at those rallies being sucker-punched to the politically and racially-motivated murder of police officers in Dallas to the throwing of Molotov cocktails at police in the state of Minnesota (where the social climate was once characterized by the term ‘Minnesota nice’)—and there is every prospect that the violence will get worse as the political season moves into full swing. Indeed, it seems that political violence is in the process of being normalized in this country. To understand the roots of this malign phenomenon, I think it is important to look at what has been going on in America’s universities for the past decade and a half.
In 2002, a pro-Israel event at San Francisco State University was interrupted by ‘protestors’, screaming things like “go back to Russia!” and “get out or we will kill you!’ and shoving Hillel students against a wall. Laurie Zoloth, a campus Jewis leader “turned to the police and to every administrator I could find and asked them to remove the counter demonstrators from the Plaza, to maintain the separation of 100 feet that we had been promised. The police told me that they had been told not to arrest anyone, and that if they did, ‘it would start a riot.’ I told them that it already was a riot.”
“This is the Weimar Republic with Brownshirts it cannot control” is how Professor Zoloth summed up the situation on her campus.
This kind of Brownshirt behavior at an American university was by no means an isolated incident: there have been many, many cases of intimidation, vandalism, and outright violence being employed against campus groups and speakers which some people–those people being almost always self-defined ‘progressives’–do not like.
At St Cloud University in Minnesota, for example, the College Republicans had a kiosk supporting Israel, complete with Israeli flag. Two professors approached the booth and asserted that since the members of the group were not Jewish, they had no right to fly the Israeli flag! One of the professors told a students that she would break his camera if he took her picture, and then tried to grab the camera–also, according to this report, also grabbed the student by the neck and slammed him up against the wall. The university administration backed the professors, also asserting that non-Jews have no right to fly the Israeli flag. (The real issue, I’m pretty sure, wasn’t that the students were non-Jewish, but rather that they were Republican.)
At Yale in 2002, some students had set up a memorial to victims of a car bombing in Israel. The memorial was destroyed by vandals. A week earlier, at the same university, a petition opposing divestment (ie, withdrawal of pension fund investments from companies doing business in Israel) was defaced–in the law school.
Theft of newspapers containing unapproved viewpoints has become common at universities. In 2004, the entire press run of the Yale Free Press, a conservative publication, was stolen by people who did not want Yale students to be able to read the opinions contained therein.
In Florida in 2004, a social sciences instructor at a community college walked into local Republican headquarters and punched a cardboard cutout of George W Bush…and then, according to this report, also punched a Republican official in the face. The punchee reports that the assailant “proceeded to say how he had a Ph.D., and he was smarter than me. I’m a stupid Republican,” and other comments laced with obscenities.
In 2006, “Protestors” of the Brownshirt variety attempted to disrupt a scheduled speech by Congressman Tom Tancredo. The chairman of the campus organization that had sponsored the event was kicked and spat upon by some of the thugs, and the building fire alarms were pulled twice.
Also in 2006, at Columbia University, left-wing students distrupted a speech hosted by the College Republicans. Angry students stormed the stage, shouting and knocking over chairs and tables and succeeding in their intent to prevent Jim Gilchrist (founder of the anti-illegal-immigration group known as the Minuteman) from delivering his talk. Columbia Public Safety did nothing to prevent the disruption. Christopher Kulawik, the College Republican president, told The New York Sun he was berated afterward by Columbia University administrators for allowing the speakers to say anything that would infuriate the crowd.
A week later, Columbia administrators interfered with another event planned by the College Republicans. The scheduled speaker was Walid Shoebat, a former PLO terrorist who saw the error of his ways and is now a supporter of Israel and the U.S. Just 3 hours before the event was to take place, a Columbia administrator sent an e-mail uninviting many of those who had already RSVP’d for the event–some of whom were already in transit. Apparently, Columbia was afraid of a repetition of the earlier disruption, and preferred to deny legitimate attendees their right to hear Mr Shoebat speak, rather than to take effective action against thuggishness by beefing up security and expelling disrupters.
In 2008, Robert Spencer spoke at U Wisconsin-Madison, on the subject of the thread from jihad. He says:
I got off the phone a little while ago with one of the student organizers of my address tonight at the University of Wisconsin-Milwaukee. He told me that I would be led to and from the stage via secret passageway; that thirty security personnel would be on hand (in addition to my own); that attendees would have to pass through metal detectors; and that a bomb-sniffing dog would also be on hand…and also: The Rushdiean security precautions and these warnings were all necessary because of the fascist tactics of trying to intimidate and shout down opponents that students and others at UWM have employed in the past against speakers such as David Horowitz.
In 2003, former Israeli cabinet minister Natan Sharansky visited several US campuses:
When I got to Rutgers University in New Jersey last month, I almost forgot I was on a college campus. The atmosphere was far from the cool, button-down academic reserve typical of such institutions. It was more reminiscent of a battlefield…Things were not much calmer at Boston University: An anonymous bomb threat brought swarms of police to the lecture hall and almost forced a cancellation of my appearance. But here, too, some good resulted when the bomb threat caused the lecture to be moved to a larger hall, which was quickly filled with some 600 listeners who were unwilling to accept the violent silencing of pro-Israel views.
During a frank and friendly conversation with a group of Jewish students at Harvard University, one student admitted to me that she was afraid — afraid to express support for Israel, afraid to take part in pro-Israel organizations, afraid to be identified. The mood on campus had turned so anti-Israel that she was afraid that her open identification could cost her, damaging her grades and her academic future. That her professors, who control her final grades, were likely to view such activism unkindly, and that the risk was too great.
Having grown up in the communist Soviet Union, I am very familiar with this fear to express one’s opinions, with the need to hold the “correct opinions” in order to get ahead, with the reality that expressing support for Israel is a blot on one’s resume. But to find all these things at Harvard Business School? In a place that was supposed to be open, liberal, professional? At first I thought this must be an individual case, particular to this student. I thought her fears were exaggerated. But my conversations with other students at various universities made it clear that her feelings are widespread, that the situation on campuses in the United States and Canada is more serious than we think. And this is truly frightening.

SHALL IT BE SUSTAINED?
See my Fourth of July post at Chicago Boyz
Sunday, July 03, 2016
One of the many tragedies of the World War II era was a heartbreakingly fratricidal affair known as the Battle of Mers-el-Kebir.
I’ve written before about the defeat of France in 1940 and the political, social, and military factors behind this disaster. Following the resignation of Paul Reynaud on June 16, the premiership was assumed by the First World War hero Philippe Petain, who immediately asked the Germans for an armistice. With an eye toward revenge, Hitler chose the Forest of Compiegne…the same place where the armistice ending the earlier war had been executed…as the venue for the signing of the documents. Indeed, he insisted that the ceremonies take place in the very same railroad car that had been employed 22 years earlier.
The armistice provided that Germany would occupy and directly control about 3/5 of France, while the remainder of the country, together with its colonies, would remain nominally “free” under the Petain government. (One particularly noxious provision of the agreement required that France hand over all individuals who had been granted political asylum–especially German nationals.)
Winston Churchill and other British leaders were quite concerned about the future role of the powerful French fleet…although French admiral Darlan had assured Churchill that the fleet would not be allowed to fall into German hands, it was far from clear that it was safe to base the future of Britain–and of the world–on this assurance. Churchill resolved that the risks of leaving the French fleet in Vichy hands were too high, and that it was necessary that this fleet join the British cause, be neutralized, be scuttled, or be destroyed.
The strongest concentration of French warships, encompassing four battleships and six destroyers, was the squadron at Mers-el-Kebir in French Algeria. On July 3, a powerful British force under the command of Admiral James Somerville confronted the French fleet with an ultimatum. The French commander, Admiral Jean-Bruno Gensoul, was given the following alternatives:
(a) Sail with us and continue the fight until victory against the Germans.
(b) Sail with reduced crews under our control to a British port. The reduced crews would be repatriated at the earliest moment.
If either of these courses is adopted by you we will restore your ships to France at the conclusion of the war or pay full compensation if they are damaged meanwhile.
(c) Alternatively if you feel bound to stipulate that your ships should not be used against the Germans unless they break the Armistice, then sail them with us with reduced crews to some French port in the West Indies — Martinique for instance — where they can be demilitarised to our satisfaction, or perhaps be entrusted to the United States and remain safe until the end of the war, the crews being repatriated.
If you refuse these fair offers, I must with profound regret, require you to sink your ships within 6 hours.
Finally, failing the above, I have the orders from His Majesty’s Government to use whatever force may be necessary to prevent your ships from falling into German hands.
The duty of delivering this ultimatum was assigned to the French-speaking Captain Cedric Holland, commander of the aircraft carrier Ark Royal.
Robert Philpott, a trainee gunnery officer on the battleship Hood: ”Really it was all very peaceful. Nobody was doing any firing; there was a fairly happy mood on board. We all firmly believed that the ships would come out and join us. We know the French sailors were just anxious to get on with the war. So we didn’t think there would be a great problem.”
André Jaffre, an 18-year-old gunner on the battleship Bregagne: ”Our officer scrutinizes the horizon, then looks for his binoculars and smiles. What is it, captain? The British have arrived! Really? Yes. We were happy! We thought they’d come to get us to continue fighting against the Nazis.”
Gensoul contacted his superior, Admiral Darlan. Both men were incensed by the British ultimatum: Gensoul was also personally offended that the British had sent a mere captain to negotiate with him, and Darlan was offended that Churchill did not trust his promise about keeping the French fleet out of German hands. Darlan sent a message–intercepted by the British–directing French reinforcements to Mers-al-Kebir, and the British could observe the French ships preparing for action. All this was reported to Churchill, who sent a brief message: Settle matters quickly. Somerville signaled the French flagship that if agreement were not reached within 30 minutes, he would open fire.
It appears that one of the the options in the British ultimatum–the option of removing the fleet to American waters–was not transmitted by Gensoul to Admiral Darlan. Whether or not this would have made a difference, we cannot know.
As Captain Holland saluted the Tricolor preparatory to stepping back into his motor launch, there were tears in his eyes. Almost immediately, Admiral Somerville gave the order to fire to open fire.
