Possibly. He certainly benefits from the talent in operation at OpenAI. Whether people come over directly like Karpathy, or via networking, or through knowledge transfer.

It could be cheaper to go through OpenAI. Other people invested in that company -- not just Musk. Also, a lot of machine learning tech and knowledge is transferrable across domains.

> Seems to me like he just actually believes in those things

He may well. I'm just saying it can also benefit his businesses to believe that AGI and fully self driving cars are coming soon.
