From the third party perspective, it feels like gambling to me. I can't imagine being ok with knowing everything keystroke you make is being tracked to train a model, most likely to replace you. I can't imagine ever wanting to work there, thought that for a long time. "It's full of brilliant people". Well, the profession is quite honestly, there are plenty of places to work.
That's changing quickly, and Meta pays extremely well.
Not so easy for 3-4 year kids out of school to make $500K-$600K.
The supergenius quanty ones go to Jane Street and the smart product-y ones jump ship to OpenAI or Anthropic (e.g. Boris) but there just aren't 20,000 high paying roles out there.
Anyone saying otherwise is kidding themselves.
