I think he is saying that if you are against AI you are against progress and so "America will no longer be the country that ambitious people want to come to". I don't think there was a point there about immigration being somehow equivalent to AI, that would come out of nowhere.

That seems like a really tenuous connection for him to make if that's what he's doing. I find it difficult to believe that ambitious people outside of a certain niche would refuse to come to the US because of perceived lack of AI progress. They'd refuse/are refusing to come because of the US's increasing hostility to outsiders, cutting of research funding, and subpar living conditions.
