Given that he leaves OpenAI almost immediately after hitting his 25% vesting cliff, it seems like his employment at OpenAI and this blog post (which makes him and OpenAI look good while making the reader feel good) were done cynically. I.e. primarily in his self-interest. What makes it even worse is his stated reason for leaving:

> It's hard to go from being a founder of your own thing to an employee at a 3,000-person organization. Right now I'm craving a fresh start.

This is just wholly irrational for someone whose credentials indicate someone who is capable of applying critical thinking towards accomplishing their goals. People who operate at that level don't often act on impulse or suddenly realize they want to do something different. It seems much more likely he intentionally planned to give himself a year of vacation at OpenAI, which allows him to hedge a bit while taking a breather before jumping back into being a founder.

Is this essentially speculation? Yes. Is it cynical to assume he's acting cynically? Yes. Speculation on his true motives is necessary because otherwise we'll never get confirmation, short of him openly admitting to it (which is still fraught). We have to look at behaviors and actions and assess likelihoods from there.
