I think it’s complicated and more tied in with your personal ambitions and passions than money. I imagine that most people making stupid money at the forefront of LLM development are probably very passionate about their work. I imagine that will make the career/person side of things much more intertwined than say… making stupid money working in finance.
It’s fairly easy to deal with bad upper management, poor organisational decision making, political infighting, silly bureaucracy, pseudo-work and a range of other nonsense when you’re mostly in it for the tech and go home at 4pm (or whenever you go home in your country). It’s quite another thing if you actually care about the mission.
