Two things labeled an eye and one thing labeled a nose and one thing labeled a mouth all add up to a face. But the classifier doesn't know what a noses, eyes, or mouths are. It doesn't know what a face is. Your doorbell camera doesn't know that the face-like thing in the melting snow on your walk CAN'T be a face, so it repeatedly warns you about a stranger on your doorstep. That theory-free-ness, combined with the abstruse mathematics of statistics, is what gets "AI" into so much trouble. Give machine learning classifiers of all the successful people at your company and it will tell you to hire people like them. But if you've been missing great people due to bias, that is terrible advice - and it's got the veneer of empiricism. Remember when AOC got tons of shit from far-right assholes for calling an algorithm racist? How can math be racist? https://www.livescience.com/64621-how-algorithms-can-be-racist.html Theory-free isn't good enough. To understand what's happening in a complex situation, you haven't to be an anthropologist, not just a statistician. You need what Clifford Geertz called "thick description" - the qualitative accounts of the quantitative phenomenon. Quantitative researchers are infamous for screwing this up. The qualitative elements are hard to do math on, so they incinerate them and leave behind a quantitative residue and do math on that, assuming it will be sufficient. It's (usually) not. That's why exposure notification isn't contact tracing: knowing that two Bluetooth radios were close to each other for 15 minutes doesn't tell you if they were swapping spit or stuck in adjacent, sealed automobiles in a traffic jam. Using theory-free inference to understand the world doesn't and can't lead to comprehension. "Theory-free" is the opposite of comprehension. We may not have a universal, agreed-upon definition of "artificial intelligence" but "understanding" is definitely a part of it. Machine-learning classifiers have done amazing things to automate away a ton of drudgery, just as smiths did amazing things to shape metal. But smiths couldn't make reliable internal combustion engines. Incremental improvements in metal-beating don't evolve into machining. Reliably turning out the precision components that produced engines needed casting and machining. Getting there required a shift in approaches, not improvement in the existing approach. Theory-free statistical inference does a lot of good stuff - and produces a lot of bad outcomes - but the idea that if we do enough of it we'll get artificial intelligence is fundamentally wrong. -------------- next part -------------- A non-text attachment was scrubbed...

I've been taking the long weekend off - my first days off since the crisis in March! - but I wanted to call your attention to an event I'm doing tomorrow. The Beaverbrook Lecture is an annual event at McGill University's Centre for Media, Technology and Democracy. Normally it's a single lecture, but this year, they've split it into two. Last week, Shoshanna Zuboff presented Part I, in which she laid out her thesis from her book IN THE AGE OF SURVEILLANCE CAPITALISM: https://www.mcgill.ca/maxbellschool/channels/event/2020-beaverbrook-annual-lecture-part-i-shoshana-zuboff-325537 Tomorrow at 9AM Pacific (12PM Eastern, 5PM UK, 6PM CET) I'm delivering a counterpoint, laying out my thesis from the short book I published last summer in response to Zuboff's work, HOW TO DESTROY SURVEILLANCE CAPITALISM: https://www.mcgill.ca/maxbellschool/channels/event/2020-beaverbrook-annual-lecture-part-ii-cory-doctorow-325538 The event is free to attend. While I wrote and delivered several speeches prior to HTDSC as I was developing it, this is (weirdly) the first new speech I've given on the theme since its publication, incorporating all the feedback I've gotten since August. It's a major new talk that I've been working on for weeks, and I'm pretty excited about it. I'm reasonably sure that they will make the video available after the fact, so if you can't make it, don't sweat it too much. Here's a podcast I did with the Centre's Taylor Owen, setting up the talk: https://www.cigionline.org/big-tech/cory-doctorow-true-dangers-surveillance-capitalism and here's HOW TO DESTROY SURVEILLANCE CAPITALISM, which is free to read on Onezero: https://onezero.medium.com/how-to-destroy-surveillance-capitalism-8135e6744d59 Cory -------------- next part -------------- A non-text attachment was scrubbed...
