I think the real issue Musk was complaining about is that sama is quickly becoming very wealthy and powerful and Musk doesn't want any competition in this space.

Hopefully some people watching all this realize that the people running many of these big AI related projects don't care about AI. Sam Altman is selling a dream about AGI to help make himself both wealthier and more powerful, Elon Musk is doing the same with electric cars or better AI.

People on HN are sincerely invested in the ideas behind these things, but it's important to recognize that the people pulling the strings largely don't care outside how it benefits them. Just one of the many reasons, at least in AI, truly open source efforts are essential for any real progress in the long run.
