Some people talk. I've been watching some of Lance Breitstein's videos. He made $100m trading but got stressed by it and figured he has enough money so now is teaching and the like https://www.youtube.com/@TheOneLanceB

I think at the moment AI trading probably works a bit but the public stuff on youtube I've come across is terrible. On the other hand Quadrature Capital paid all their staff £2.8 million bonuses because they had so much money rolling in. Google's thing says they are a "secretive London-based, AI-driven quantitative proprietary trading firm".
