She’s saying that when you use social media, only like, read, etc., stuff that you want to learn from or you like listening to. Scroll past the flight or flight stuff, that’s the story they want for you. Your feed will quickly be a nice place to hang out and it will poison their data.

Data poisoning can go a lot further than this. There are fascinating (and hilarious) videos by people who poison their music with inaudible (to humans) noise which, when it’s stolen by an AI company and used to train a model, will cause the model to output unintelligible garbage. Images can also be manipulated this way so that the model sees a completely different image than the human. Then there are the Nepenthes traps for AI data trawlers which trap the trawlers in an inescapable web of nested webpages of nonsense. The future is bright.
