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.
