I saw the movie you're talking about. It was called WarGames and came out in 1983.
But forty years later, killer drones are all over the place.
"imagine some worst case scenarios that end in global thermonuclear war"
Ok, sure, I can't really imagine it but I can't rule it out.
What I can't imagine is somehow everybody waits around for it and doesn't use similar AI for immediate needs in ongoing wars like in Ukraine.
And I can't really imagine AI that launches all the nuclear missiles causing global thermonuclear war, purely in a semantic sense, because whoever set up that situation would've launched them anyway without the AI.
Ok course we keep humanizing these thoughts, while we're creating more capable digital aliens every day. Then one day we'll act all surprised for a few minutes when we've created super powered digital aliens that act nothing like we expect, because the only intelligence we see is our own.
"Imagine" is a word that has more than one sense. I can "imagine" a possibility whether or not I think its probability is > 0%. Saying "I can't imagine" can be a way of saying yeah, I think the probability is 0%.
But if I can state the probability, I must have some kind of model in my head, so in that sense I am "imagining" it.
"Imagine" that strategic bombing was invented, and then everybody just waited around without doing it until there was a bomb that could destroy an entire city - i.e. Trinity.
In one sense, sure, I/you/we can imagine it. But it seems to me that sort of thing would be unprecedented in all of human history, so in another sense it seems impossible - unimaginable - although in a softer way than a violation of physics or logic.
The last bit of my previous comment was about logical impossibility, by the way.
