Multiplicity

"What would you tell them in 1983 about the development of the internet in 1983, knowing what we know now?" David Post asked in a panel on robotics governance at this week's We Robot conference. (My write-ups from previous years: 2013, 2012) Kristen Thomasen, whose paper proposed using the automobile industry as a source of lessons for how the law should consider robots, suggested creating an international body that could identify and collaborate on cross-border problems as they arose.

My first thought was that I'd tell them to expect abuse because community does not scale. (It seems like small beer, but the early days of the internet were marked by such giddy communitarian hive-mind-is-wonderful hyperbole.) Post led the discussion to broader questions: if you're going to intervene in the development of new norms and law, when do you do it? How do you do it while remaining flexible enough to allow the technology to develop? Particularly with respect to privacy and teens' willingness to share information in a way that scares their elders, "Could we have had that conversation in 1983?"

This is the heart of We Robot: the co-chairs, Michael Froomkin and Ryan Calo run the conference precisely to try to get ahead of prospective conflicts. froomkin-r2d2.jpgSo Froomkin's answer to Post's question was to note that being "in the room" matters. Had "just one lawyer" been present when engineers were creating the domain name system its design could have been different because that lawyer would have spotted the issues we have been grappling with ever since. "People with different backgrounds and perspectives spot problems," he said, "and also solutions." And, he added, those changes are easier at the beginning, when there's less deployment and less money invested.

Thomasen had a good example ready to hand: the frame still commonly used for cars was not developed for safety but because the French designer who invented it thought it looked good. "If he'd been thinking about safety, he would have used arm brakes," she said, "because they're faster than feet." But the original design is the norm we all know, and changing it now would be about as feasible as replacing all the world's keyboards with Dvorak models.

This year's conversation reflected the more general rise of interest in robot governance. The Brookings Institution, for example, has recently published two relevant reports. The first is by Calo, arguing the case for a Federal Robotics Commission (in a conference paper, Woody Hartzog suggested the FTC might be an appropriate regulatory agency); the second is by Carnegie-Mellon PhD student Heather Knight discussing human responses to robots and advocating "smart social design". The two reports are helpfully summarized at Robot State. Internet pioneers were notoriously resistant to the idea of regulation; the issue looks different when you're talking about machines that interact with the physical world.

In deciding how the law should treat robots, how much does it matter if we anthropomorphize them? While largely accepting Bill Smart's characterization of robots at the first We Robot as "really fancy hammers", Kate Darling's paper discussed situations in which anthropomorphization might be useful. Could, she asked, robots be used in a prison context to rehabilitate or console? I'm of the fancy-hammers school myself - discussions of robots having sentience or rights rapidly brings out my inner biological supremacist. Ken Goldberg, discussing Darling's paper, noted stories that in the military there have been cases where humans have put themselves at risk to protect robots that had previously saved the lives of their peers. "How do we design the system to avoid that?"

Goldberg's suggestion, later echoed in comments by Tony Dyson, the designer of the original R2D2, was to design things that are "just anthropomorphic enough". R2D2, which Dyson designed for comedic, rather than practical, function, is a case in point: it looks nothing like a human, yet is beloved. "I don't think anyone falls in love with C3PO," Dyson told me, noting that he has had hundreds of emails from people who say they now work in robotics because of R2D2.

Darling's studies of interaction with and empathy for robots expose interesting gaps in human reactions, as did the conference itself. An enterprising Irish farmer has demonstrated using a drone instead of a sheepdog to herd a flock. Is this more or less sad than reading calls to replace human pilots with automated flight systems in the wake of the Germanwings crash? It's worth noting a pilot's rebuttal of this notion: even when they're not directly flying the plane, pilots work plenty hard. The dichotomy immediately reminded of Tom Paxton's song, Don'tt Slay That Potato: "Do you mean to say you'll eat us [potatoes] because we're not cute?"

Goldberg also noted the recent Moore's Curse article, which argues that the exponential increase in computing power over the last 20 years has led to unrealistic expectations. "Technology is a sigmoidal process," he said. "Reality is lagging quite far behind science fiction." Instead of the Singularity, Goldberg believes "the Multiplicity" is a better and stronger idea: many diverse machines working together with many humans is far more powerful. "What's important to make it work is diversity."

Revelations

In the February 2, 2015 issue of The New Yorker, the writer Alec Wilkinson begins an otherwise excellent article on the mathematician Yitang Zhang's success at solving a century-old mathematics problem this way:

I don't see what difference it can make now to reveal that I passed high-school math only because I cheated. I could add and subtract and multiply and divide, but I entered the wilderness when words became equations and x's and y's. On test days, I sat next to Bob Isner or Bruce Gelfand or Ted Chapman or Donny Chamberlain - smart boys whose handwriting I could read - and divided my attention between his desk and the teacher's eyes.

Without wishing to be humorless about this - and admitting that in high school math was my *best* subject and I never thought I had any talent for writing - and while agreeing that this is, in its way, a refreshingly honest personal story that I would hate to see turned into an excuse for public shaming and a morality play...

Why is it acceptable for a writer in a major publication to say he cheated at math? Let's try that sentence some other ways. "I don't see what difference it can make now to reveal that I only passed high school English because I cheated." "I don't see what difference it can make now to reveal that I only passed high school Spanish because I hacked into the school's computer system and changed my grade." "I don't see what difference it can make now to reveal that I only made my high school rugby team because I took steroids."

We probably don't assign the same level of "badness" to those scenarios, but they all ultimately have the same effect: someone was awarded the rights that come with passing tests while avoiding the specified work assignments and consequently was accepted into whatever came next. Logically, in all those cases someone else lost the place taken by the person who cheated. Granted, Wilkinson's biography shows jobs won on merit, not credentials; before becoming a staff writer at The New Yorker he was a policeman in Wellfleet, Massachusetts, and before that a rock and roll musician. You can't conclude that if he hadn't cheated at math he would not be an award-winning writer now.

But Wilkinson's career trajectory isn't what's bugging me. Instead, it's his presentation, and its acceptance by The New Yorker's editors, of this transgression as an entertaining opening gambit. The New Yorker, which prided itself for decades never (well, hardly ever) publishing an inadequately checked fact or a typo!

The also story reflects a truly damaging attitude: math is hard, no one really needs it, and cheating at it (or dropping it from the curriculum) is OK. Instead, algebra, on which Wilkinson foundered and which in 2012 was dismissed even more readily by Andrew Hacker in The New York Times, teaches abstract thinking and problem-solving. These are assets in every society in every era. Granted, Wilkinson grew up to write about the very complex problem that Zhang solved with a no doubt hard-earned comprehension of detail, and the irony of Wilkinson's opening gambit is not lost on me. But although you might argue that The New Yorker's value for mathematics was shown by its decision to publish this piece, the *story* was that familiar American trope of the lone wolf who solves a problem that has long defeated better-acknowledged experts. Every publication loves that story, no matter what the field.

Hacker's argument, which does at least advocate teaching statistics and the ability to understand and critically evaluate the numbers in use all around us, seems to me to blame mathematics for teaching and social failures. The statistics he quotes show that math is a major stumbling block for enormous numbers of kids. In a 1990s interview, Cochrane-new-casual4-big.jpgPeter Cochrane, the former head of BT Research, told me he was one of those kids. Having failed the 11-plus exams, he had to return to night school to get through the math barrier to build his fine career. If even bright, highly motivated kids have this trouble, shouldn't we look elsewhere for the source of the problem? Perhaps beginning with the repeated attitude, from parents, school teachers who self-select away from math, and TV shows and media all around, that math sucks.

Asked his view now by email, Cochrane was robust: "You can't do security without algebra or indeed electronics and many other topics." He added, "Choosing education courses that are easy gets you to the UK situation where all the baristas in my local coffee shop have degrees in sociology, media studies, political science, business studies et al! Not one of them has a future and not one of them will ever contribute to the generation of the GDP. They have no profitable future ahead of them and a debt mountain from their education costs. What a waste!"

I would argue that we still need sociologists, political scientists, and even (sigh) people with business degrees. But I'd like them to understand the basic rules of logical thought. Maybe The New Yorker can take the view that cheating to pass high school math doesn't matter because they don't perceive that as happening to *them* in the way that plagiarism would. But the lack of society-wide logical problem-solving ability certainly is happening to all of the rest of us.
