But with cars there is an upside, we tolerate it because it is so usefull and the government does its best to make it as safe as possible, setting requirements that need to be met for you to legally use it.
In this case there isn't that much upside, it's basically only being used for non-consensual porn generation and impersonating people
Then, it's going to be pretty hard to defend that the "downside-related" usage and the "upside-related" usage are anywhere near each other in terms of volume.
To be clearer: yeah, some people are probably creating deepfakes of their own, consensual GFs somewhere on the planet - and more fun to them. There are also comedians doing great things with that.
But let's not kid ourselves into the actual, massively majoritary usage: making someone else's life just a tad shittier, either for profit or out of pure meanness.
I don't know if there is academically sanctionned data about it to appease the HN-crowd, but when it comes out and says "yeah, statistically, talented comedians and kinky couples are only a fraction of the scammers and revenger-p.rn users.", don't count me suprised.
