We can't even get people to look for a green lock icon in their URL bar. I really doubt the kinds of people that are most vulnerable to these attacks will suddenly develop an interest in cryptography.

And if the fake confirms someone's worldview or serves their interests, confirmation bias will take over and no "fancy math" is going to change their mind.

I don't think we'll adapt "suddenly," I expect we'll have to experience some major news stories getting redacted due to deepfaked evidence before this reaction becomes mainstream, but I think it's coming. I also don't think an interest in cryptography is necessary, it's not like I expect people to read public keys directly. There will be some system that shows something along the lines of "Confirmed by $USER_NAME" under the media. You don't need an interest in video codecs to appreciate YouTube. And I have seen people reject faked evidence, such as fake screencaps of tweets, even when it backed up their worldview. We're not perfect at it, but I think we're getting better.
