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.

Upcoming changes

From today, I’m making some small changes in this blog, basically to tidy things up. From now on all posts written on the same day will be included on a single page, with Quotes and the Linkblog at the end, and a permalink for each element. In practice it should make for easier reading, and it might also make it easier to create an email version for readers who prefer getting it in their inboxes.

If you have been, thank you for reading.

Maternal scepticism

Dave Winer writes:

A family story. My mother was a pure capitalist. She believed in hard work, being productive. She felt threatened by evidence of idleness. I drove her crazy. Even as a kid I would sometimes just sit in a chair in the living room of our apartment in Jackson Heights and think. Once she saw me sitting, lights off, no TV, no book, appearing to be doing nothing, and she lost her shit right there. Anyway, many years later, when I sold my company and then it went public, after years of begging me to get a job, her stock in the company was all of a sudden worth a lot of money. It was the only time I remember getting her unqualified approval. She boasted, even when I could hear, that I was profitable. In other words, the money and time she put into raising me made her money.

That rings a bell. I’ve been a journalist and an academic all my working life. (My Observer Editor-in-Chief, Conor Cruise O’Brien, who straddled the same two occupations with great distinction, once said to me that he and I “had a foot in both graves”.) My mother, who hoped I would become an engineer with the national Electricity Supply Board, went to her grave believing that I never had held a proper job.

So Harry and Meghan are spinning themselves off from The Family Firm. The Economist provides the stock market analysis

Harry and Meghan’s move was announced without consultation with the group’s management, but may have been encouraged by developments within it. The stock price has tumbled recently, as a result of missteps by Prince Andrew, who has now been fired. Prince Charles—who will take over the top job in the not-too-distant future—has hinted that he plans to cut costs and slim down its operations as part of a broader restructuring. Rather than wait for that shake-up, Harry, who knew he was unlikely ever to get the top job, has now decided to cut loose.

This separation has the advantage of strategic clarity, and is likely to unlock value, given that the Harry and Meghan brand was widely perceived to be undervalued. The new entity will now have more freedom to diverge from the positioning of the parent group and to tap overseas markets. The couple say they plan to divide their time between Britain and North America.

Seasonal compassion

I’ve always been ambivalent about Christmas. Because my parents were’t very good at celebrations, my childhood experience of the festival was often one of disappointment. When I met Sue, my late wife, I had to change my views because she really loved Christmas and took great delight in every part of it, and our children learned that from her. But I remain acutely aware of the stresses it puts on people who are poor, unhappy or depressed, when the contrast between their own conditions and the glitzy, showy, consumer-driven atmosphere all around is painful. So it was sweet to find this message on one of the main pedestrian bridges across the Cam this Christmas.

Practice makes perfect

Tyler Cowen, the economist, is one of the most interesting public intellectuals around. His blog is a marvel (and a daily visit for me). His capacity to absorb ideas is remarkable. And he is fearsomely productive. So how, one wonders, does he do it?

This week he shed some light on how he works:

  1. I write every day. I also write to relax.

  2. Much of my writing time is devoted to laying out points of view which are not my own. I recommend this for most of you.

  3. I do serious reading every day.

  4. After a talk, Q&A session, podcast — whatever — I review what I thought were my weaker answers or interventions and think about how I could improve them. I rehearse in my mind what I should have said. Larry Summers does something similar.

  5. I spent an enormous amount of time and energy trying to crack cultural codes. I view this as a comparative advantage, and one which few other people in my fields are trying to replicate. For one thing, it makes me useful in a wide variety of situations where I have little background knowledge. This also helps me invest in skills which will age relatively well, as I age. For me, this is perhaps the most importantly novel item on this list.

  6. I listen often to highly complex music, partly because I enjoy it but also in the (silly?) hope that it will forestall mental laziness.

  7. I have regular interactions with very smart people who will challenge me and be very willing to disagree, including “GMU lunch.”

  8. Every day I ask myself “what did I learn today?”, a question I picked up from Amihai Glazer. I feel bad if I don’t have a clear answer, while recognizing the days without a clear answer are often the days where I am learning the most (at least in the equilibrium where I am asking myself this question).

  9. One factor behind my choice of friends is what kind of approbational sway they will exercise over me. You should want to hang around people who are good influences, including on your mental abilities. Peer effects really are quite strong.

  10. I watch very little television. And no drugs and no alcohol should go without saying.

Sex sells, apparently

Well, what do you know? the best-selling book over the last decade was E.L. James’s 50 Shades of Grey, which which sold 15.2 million copies from 2010 through 2019. It was originally self-published as a Kindle ebook and print-on-demand publication in June 2011; the publishing rights were acquired by Vintage Books in March 2012. Smart move. I wonder what they paid for them.

Boeing’s idea of reassurance

Source: New York Times

Boeing’s 737MAX remains grounded (rightly) as the company struggles to overcome the design flaw that caused two crashes that killed everyone on board. In the meantime, Boeing has been surveying airline passengers across the world to assess their thoughts about flying in the MAX once it gets certification. The news is not good, according to this report in the New York Times: people are nervous about flying in the plane. In order to get ahead of the problem, Boeing has been preparing draft briefing materials for airline staff giving guidance on how to soothe and reassure nervous passengers. Above is a draft of the crib-sheet that’s been obtained by the Times.

As you’d expect, it’s an exercise in consumer manipulation.

This has a personal dimension for me. The place to which I most often fly is Ireland. And the only way to get there from Stansted, my local airport, is via RyanAir. But RyanAir plans to replace its existing fleet of Boeing aircraft with 737MAXs. So will I trust the Federal Aviation Administration enough to continue flying RyanAir? Or will I have to plump for much less convenient alternatives?

Hmmm…
