My best friend and I took him on a ski trip when he had just sold Loopt. I've been connected to him since. He's always very responsive via texting and was stoked to receive copies of the book I wrote with AI when OpenAI gave me researcher access years ago. I haven't worked with him on a team however.

* the book was Autonomous Haiku Machine; and was the first book of haiku written by AI.

I can guarantee you he is competent.
