I'm not scared about AI recommending nuclear strikes, I'm scared about the human behind the keyboard delegating reasoning and responsability to something they think is always correct, something that can hide bias and flaws better than anything.
Some of the most reassuring and scariest things you can read are about the incidents that have already occurred where computers said "launch all the nukes" and the humans refused. On the one hand, good news! We have prior art that says humans don't just launch all the nukes just because the computers or procedures say to. Bad news, it's been skin-of-our-teeth multiple times already. https://www.warhistoryonline.com/c…
It's not just nukes that are concerning either. If we're unable to mitigate such a visceral existential risk, we aren't going to do any better with more subtle vulnerabilities. AI of course accelarates some risks and introduces new ones.
This doesn't mean we're doomed or anything, but if I had a magic portal to peer a few hundred years in the future and saw humans had been obliterated by nukes, runaway AI, some generated supervirus, runaway climate change, or some other manufactured risk I would be completely unsurprised.
