EU has almost no AI, yet is the world leader in AI .... regulation. No upstart social network would have the funds to ensure GDPR compliance and all the other rules that get added along the way. If someone has a business idea for one, they move to the US cause it's easier to start. Mistral AI is expanding to California. The solution would be less bureaucracy and regulation.
DeepMind was EU based, for example, before Google bought them. When I worked three, they were still London based (and in EU). Are they American now? American capital controls most of the AI, but that doesn't mean Europeans are incapable of AI research.
Also I think the push for AI alignment is American. At least three AI alignment people somehow always think that forcing I to adopt American values of the only correct and moral thing to do. Isn't that similar?
