He’s the CEO of OpenAI, which is responsible for the most-discussed advancement in technology for the past year. So it’s not that unusual for this to be discussed on a technology-focused forum.
He’s also the centre of a massive firestorm, where extremely atypical corporate behaviour was very recently taking place. Again, highly relevant topic for a forum that deals with startups.
In short, it’s news, and specifically news of interest to people on this site. No need for cults or obsession.
