> One thing odd, maybe just to me, is why OpenAI has been stuffing its ranks with former Facebookers who are known to juice growth, find edges, and keep people addicted

There is a very simple answer for this: that’s how leadership ranks work in SV. When one “leader” moves from Company A to Company B, a lot of existing employees are pushed out or sidelined, and the ranks are filled with loyalists from previous companies. Sometimes this works out, but a lot of time it doesn’t and it stays that way until another “leader” is brought in. What’s good for the company doesn’t matter unless there clear incentives and targets lined out for them.
