OpenAI is a very dynamic company. As someone with an inside experience of the dynamics that lead to people swapping in and out, my own view is that while it can be stressful for the people involved, by and large it is healthy for the organism of the company. It makes it unusually capable of responding to changes in technological or market conditions - conditions which change frequently given the exponentially fast nature of the technology. It is part of why OpenAI can be counted on to succeed. It doesn't allow internal fiefdoms or empires to persist indefinitely, it doesn't allow a single way of thinking to outlive its ability to get the job done, it doesn't stagnate. The mission persists but everything about how to execute it has extraordinary fluidity. Every individual departure is a loss for the company and yet the aggregate of the departures makes the company dramatically more resilient, and eventually, focused.
