FWIW, leaving aside his professional activities (such as the fact that he's currently the co-founder of two AI startups) he is probably the first billionaire to create an "AI clone" of himself, complete with a deepfake video avatar and voice-cloning, trained on all the content he has ever produced (books, articles, interviews, videos):
The interviews are not real-time and are heavily edited, of course, but he's probably one of the few tech execs who've spent so much money and time to personally explore AI.
His LinkedIn profile lists manas.ai, which is pretty new, and inflection.ai, which has been around for a few years. Inflection released Pi, which was the first chatbot I encountered that kept conversations very interactive by asking clarifying and follow-up questions, whereas ChatGPT and others were very transactional.
However it is probably known more (if at all) for being the company Microsoft "Windsurfed" by licensing all its tech and poaching its leadership team, including the dude who's the current "CEO of AI" at MSFT.
