The only good arguments I see against open weight AI also apply to closed AI. And regardless, the box is open, nobody can stop it even if stopping it was a good thing.
I think they've certainly diminished racism, which is a good thing. Whether it can be solved is another question entirely. I doubt it because of human nature.
I disagree. I’ve actually seen more open racism since the taboo on racism became stronger. In a pluralistic society, they are overrated as a way of influencing social behavior. You’d have to completely eliminate the faction who disagrees with the taboo.
