>> What evidence is there that deepfakes are harmful and not just distasteful?

Further down the thread there is an example of a political deepfake used to spread disinformation. I don't really care about distaste, it's authenticity (the truth) that is under attack by these. On the upside, they can offer a bit of entertainment.

It's not even a problem of regulation since the bad guys will always have deepfakes. The cat is out of the bag already.
