Deep fakes automate what deep pockets and state actors could already do with Photoshop and other professional tools. The world isn't going to become a scary place because the barrier to entry got lower and the technology has been democratized. People are smart. Fakes will be detectable through entropy measures, corroboration, common sense, etc.
FWIW, I've been working on real time voice to voice style transfer.

It's also amusing (and terrifying) to see all the anti-1st Amendment legislation aimed at combating deep fakes. The truth is that there is nothing to fear except our freedoms being taken away.
