The same self-driving company he left? His "Amazing Journey" post[1] for Comma was illuminating; once a company is "[...] no longer a race car, [but] a boat" GeoHot is likely to bounce. I like AMD as much as the next guy, but I don't want to rely the software being provided by a personality who only really gets excited by working on new projects before the "wild success" stage (if we can call it that for Comma)

He is still a part of Comma, as far as it seems, he is just by his own admission not the best guy to lead a company that got big enough for him and which needs certain stability and adhere to certain bureaucracy if you will. In some way, I think it's rather admirable that someone knows when to move aside and let others take the lead.
It's not like he decided to hop from self-driving cars to 'AI' because fads changed.
