You realize a person can train and run their own AI models, right? So we're not even just talking about governments deciding to stop. The AI genie is out of the bottle.

It's also worth noting that you fear Elon Musk, who is a major US defense contractor, more than China because "If the world's financial markets and global economy collapse, China and everyone loses.". You don't think the world's richest man would also lose in this scenario?

Pretty obvious you are running on pure fear and propaganda and haven't put much rational thought into this.

"Someone do something, I'm scared!"
