People with some degree of knowledge already know that any photo could be photoshopped. People that don't care will blindly trust a picture of someone with a quote or caption saying whatever, as long as it fits their narrative.

This has been the case for photos for almost 2 decades. The fact that you can now do it with video or audio doesn't change that much IMO.

I think it does, because while you obviously couldn't trust images since two decades or so, you could resort to video which wasn't easy to believably deep fake until recently. But if everything online could be a deep fake, how can you find out the truth?

Videos can be faked too, it is just cheaper now.

It's called special fx, is more than a century old (people are now aware it's fake but remember the word is that the train coming in la ciotat movie made people run out of the movie theatre).

Photos have been altered for much longer than 2 decades. Think of airbrushing models in magazines (used to be literal airbrushes painting over photos). This has had a serious impact on our perception of beauty and reality.
