2 big impacts I think deepfakes will have.

1. Internet mobs will be de-clawed and any random person on the street that may have had their private information used against them now has instant plausible deniability. This is a big step towards valuing due process and personal privacy as digging into people's personal histories will become far less valuable than before if it can simple be handwaved away.

2. This could be a step back from the balkanization of the media. If anything can be faked than personal reputation and organizational reputation will be become far more valuable when it comes to the spread of stories.
