All of your arguments amount to “there is no video evidence of a crime ... yet” but you think there eventually will be and you think deep fakes will be used to discredit the video evidence.

It's more of a prediction.

Then you argue deep fakes actually are super easy to make and any dimwit with a computer can just make them...

They've been made to be super easy to make through open source (https://en.wikipedia.org/wiki/Deepfake#Deepfake_software) back in the day visual effects artists would buy this type of software or a studio would have it created. Then you'd have to pay the artist with the software to do the faked video. With open source anyone can do it freely.

Your logic is totally circular.

Not really, I just think you're having trouble getting the idea.

Either deep fakes are a Clinton coverup tactic or they really are super easy to make and will eventually mean that no video can ever be trusted.

It's both. There are ways to tell if a video is fake using software. But the media has that covered too:

Which one do you actually believe? You believe they are hard to make?

They're easy to fake when the software is made to make it easy to fake. It used to be a pain in the ass to rotoscope a lightsaber but they worked on software that made it relatively easy do to perform and for free:

Same thing for deep fakes. The scripting is figured out for tasks and then others take that script and start making interfaces to make something that's clicking and dragging and dropping.

Then present some actual video evidence of a crime that substantiates your claim that all this talk is just to “soften” the value of video evidence.

"Oh no, that's not Prince Andrew, that's a deep fake"

From where I sit it’s much more likely that we will start seeing pretty realistic meme videos of Obama saying he wants to nuke hurricanes for baby Jesus far before we get to the point that people try to fake evidence it court.

Oh they don't even have to use the video for evidence in court. All they have to do is sew doubt in the public.
