So what's going on? Now, YouTube's algorithm is proprietary, but here's what I think is going on. The algorithm has figured out that if you can entice people into thinking that you can show them something more hardcore, they're more likely to stay on the site watching video after video going down that rabbit hole while Google serves them ads. Now, with nobody minding the ethics of the store, these sites can profile people who are Jew haters, who think that Jews are parasites and who have such explicit anti-Semitic content, and let you target them with ads. They can also mobilize algorithms to find for you look-alike audiences, people who do not have such explicit anti-Semitic content on their profile but who the algorithm detects may be susceptible to such messages, and lets you target them with ads, too. Now, this may sound like an implausible example, but this is real. ProPublica investigated this and found that you can indeed do this on Facebook, and Facebook helpfully offered up suggestions on how to broaden that audience. BuzzFeed tried it for Google, and very quickly they found, yep, you can do it on Google, too. And it wasn't even expensive. The ProPublica reporter spent about 30 dollars to target this category.

This isn't "1984." Now, if authoritarianism is using overt fear to terrorize us, we'll all be scared, but we'll know it, we'll hate it and we'll resist it. But if the people in power are using these algorithms to quietly watch us, to judge us and to nudge us, to predict and identify the troublemakers and the rebels, to deploy persuasion architectures at scale and to manipulate individuals one by one using their personal, individual weaknesses and vulnerabilities, and if they're doing it at scale through our private screens so that we don't even know what our fellow citizens and neighbors are seeing, that authoritarianism will envelop us like a spider's web and we may not even know we're in it.
