Solipsism, to quote Wikipedia: is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind.
GenAI reduces what once was photo/video/audio proof to uncertainty both through quality (AI can create better fakes) and quantity (it is much easier to use AI to create fakes, therefore much more people will do so).
I can make an AI Fake that Donald Trump has two heads.
It could look convincing.
It would not take much effort to disprove that.
It's not clear to me why this is any bigger than rumors and propaganda and gossip. If you're susceptible to that, you're susceptible to deep fakes, but you were already trapped in a bed of lies.
I still maintain that it has never been easier to seek the truth than today.
You've fallen into a trap where you 'know' you'll recognize the truth when it occurs because 'reasons'. It's the wrong way to look at the problem. Instead say "How much energy/time am I going to spend debunking bullshit", because once it's more time/energy then you have, it's game over.
We’re just going to open the field of convincing looking bullshit to a whole bunch of newer and even more nefarious interests.
Basically agreeing with you though.
And if you rely on the “everyone knows people can only have one head” heuristic to validate the one-head hypothesis, that isn’t evidence seeking, it’s confirmation bias.

I'm also not an expert but that's what I understood from the original comment. Hope this helps
