This is one of my favourite YouTube videos. Shows you what real mastery is like. Unshowy but unforgettable.


Clearview: the astonishing (but predictable) story

The New York Times had a great story the other day about a tiny firm called Clearview AI which had crafted a program to scrape images of people’s faces from across the Web — employment sites, news sites, educational sites, and social networks including Facebook, YouTube, Twitter, Instagram, etc. — and built a facial recognition algorithm that derived from academic papers. When a user uploads a photo of a face into Clearview’s system, it converts the face into a vector and then shows all the scraped photos stored in that vector’s neighborhood — along with the links to the sites from which those images came. Basically, you upload a photo and in many cases you get a name — often from a social-media posting.

Not surprisingly, police forces seem to like Clearview. One possible reason for that is that its service seems to be unique. Would-be imitators May have been deterred by the fact that the main social-media sites prohibit image-scraping, something that doesn’t seem to have bothered Clearview. Either that or they had a lawyer who knew about the LinkedIn case in which LinkedIn tried and failed to block and sue scrapers. The company lost the case and the judge said that not only could they not sue, but also that they’re not even allowed to try to block scraping by any technical means. As Ben Evans, observed, “Some people celebrated this as a triumph for free competition and the open web – welcome to the unintended consequences”. This case also confirms that facial-recognition technology is becoming a commodity.

Interestingly, Peter Thiel is an investor in, and a board member of, Clearview.

UK government policy on electric vehicles is based on magical thinking

Take, for example, the UK pledge to move entirely to electric vehicles by 2050. I’ve been puzzled for a while about the electricity-generation capacity that would be needed to charge all those vehicles. And then I stumbled on a remarkable letter from a group of relevant scientific experts about the resource implications of such a commitment which was sent to the IPCC in June last year. And I realised that generation is only a smallish part of the story.

It’s well worth reading in full, but here are some of the highlights. To meet UK electric car targets for 2050 the UK would need to produce or acquire just under two times the current total annual world cobalt production, nearly the entire world production of neodymium, three quarters the world’s lithium production and at least half of the world’s copper production. Oh – and 20% increase in UK-generated electricity would be required to charge the current 252.5 billion miles to be driven by UK cars.

Like I said, magical thinking. Wishing doesn’t make something happen.


Could Mike Bloomberg beat Donald Trump?

Maybe. At least he’s rich enough. But be careful what you wish for. As Jack Shafer neatly points out, Bloomberg is a surveillance addict. A guy who amassed a $54 billion fortune by collecting petabyte upon petabyte of sortable data, would be very keen on enhancing a high-tech surveillance state that would collect personal data as aggressively and as expansively as he and his company do financial data.

Dennis Hopper was a great photographer. Who knew?

Not me, anyway. But last month Mark Rozzo had a fabulous piece in the New Yorker about a new collection of Hopper’s photographs edited by the photographer Michael Schmelling, to whom Marin Hopper (Dennis’s daughter) granted unlimited access to the archive. Hopper received a Nikon F as a gift on his twenty-fifth birthday, in May, 1961, from the actress Brooke Hayward, who would become his first wife. Her father, the agent and producer Leland Hayward, was “a camera nut”, and Brooke paid $351 for it. (Don’t you just love the fact-checked precision of the New Yorker — right down to that last buck!) “Dennis had the greatest eye of anyone I’ve ever known,” Hayward told Rozzo for a story he wrote last year about her marriage to Hopper. “He wore the camera around his neck all day long.” Some of the shots that illustrate the piece are really terrific. Result: one book sold to this blogger. It also reminded me that I have a Nikon F2 that badly needs servicing. Now where did I put it…?

Joe Biden really doesn’t like Silicon Valley

I’m beginning to warm to him. The NYT team did a really extensive on-the-record interview with him (transcript here). Here’s an excerpt from a passage where he’s been asked about his experience of dealing with Facebook about some stuff published on the platform containing false claims that he had blackmailed Ukrainian officials not to investigate his son.

Biden: I’ve never been a fan of Facebook, as you probably know. I’ve never been a big Zuckerberg fan. I think he’s a real problem. I think ——

Charlie Warzel (NYT guy): Can you elaborate?

JB:I can. He knows better. And you know, from my perspective, I’ve been in the view that not only should we be worrying about the concentration of power, we should be worried about the lack of privacy and them being exempt, which you’re not exempt. [The Times] can’t write something you know to be false and be exempt from being sued. But he can. The idea that it’s a tech company is that Section 230 should be revoked, immediately should be revoked, number one. For Zuckerberg and other platforms.

CW: That’s a pretty foundational law of the modern internet.

JB: That’s right. Exactly right. And it should be revoked. It should be revoked because it is not merely an internet company. It is propagating falsehoods they know to be false, and we should be setting standards not unlike the Europeans are doing relative to privacy. You guys still have editors. I’m sitting with them. Not a joke. There is no editorial impact at all on Facebook. None. None whatsoever. It’s irresponsible. It’s totally irresponsible.

CW: If there’s proven harm that Facebook has done, should someone like Mark Zuckerberg be submitted to criminal penalties, perhaps?

JB: He should be submitted to civil liability and his company to civil liability, just like you would be here at The New York Times. Whether he engaged in something and amounted to collusion that in fact caused harm that would in fact be equal to a criminal offense, that’s a different issue. That’s possible. That’s possible it could happen. Zuckerberg finally took down those ads that Russia was running. All those bots about me. They’re no longer being run.

That’s interesting. Revoking Section 230 is the nuclear option in terms of regulation. It would reduce Facebook & Co to gibbering shadows of their former selves. And of course provoke hysteria about the First Amendment, even though Facebook has nothing to do with the Amendment, which is about government — not corporate — regulation of speech.

The EU is considering banning use of facial recognition technology in public spaces

According to Reuters, a White Paper by the European Commission says that new tough rules may have to be introduced to bolster existing regulations protecting Europeans’ privacy and data rights. During that ban, of between three to five years, “a sound methodology for assessing the impacts of this technology and possible risk management measures could be identified and developed.” Exceptions to the ban could be made for security projects as well as research and development.

Why are Apple & Google wanting you to use your phone less?

Nir Eyal (the guy who wrote the book on how to create addictive apps and subsequently seems to have had an attack of developer’s remorse) argues that it’s because they are trying to get ahead of users’ concern about addiction. He sees it as analogous to what happened with seat belts in cars.

In 1968, the Federal Government mandated that seat belts come equipped in all cars. However, nineteen years before any such regulation, American car makers started offering seat belts as a feature. The laws came well after car makers started offering seat belts because that’s what consumers wanted. Car makers who sold safer cars sold more.
