Before these developments it was impossible to fake a politician saying arbitrary stuff. This is a major shift, there's no denying that.

That's the thing though, it wasn't impossible, just harder - but people believed whatever they saw, so it was done regardless of the costs. Now it's easier and people are finally getting sceptical, as they should've 20+ years ago.

Deep faking voices has been real and super easy for years via 11labs etc. This doesn’t change that at all.

Voice impersonation has been possible forever, actually; and it use for misinformation (as well as less nefarious things like entertainment) is hardly novel. (Same with impersonation that goes beyond voice.)
