I disagree with you about the guy as a person, I think he's great, but I was considering working there and his requirement that you have to move to SV and work in the office was a deal breaker. The guy seems to understand how our kind of work can be done from anywhere, he seems interested in developing technology to enable self sovereignty, yet it seems he has blinders on on that one issue. I'm sure he has some reasoning for it and I'd love to hear it, I doubt it's convincing but if it's him at the very least it will be novel or interesting (I hope).

he understand so much and interested that he is quitting. Why not stick thru with it?

He explains it in the article. He's the kind of guy that's good at following through when it's exciting, when it becomes a chore he's more a liability than an asset, so he's handing it over to people who can follow through, he's contributed all he can. Paraphrasing.
