The disincentives to nuclear war are glaringly obvious enough that even politicians (and their masters) get it.

AI isn't like that. One problem is that it's rather generally misunderstood at this point. "AI" is not "intelligence". It's intelligence-adjacent, and something like LLMs is part of our psyche...the subconscious facility that allows us to form sentences without really thinking about it.

At any rate, I have to agree with most of the points the blog author brings up.

I mean, not really. The only reason we've not died in a nuclear war is building nuclear bombs is very very difficult and expensive. If suddenly it became quick and easy to get nukes, we'd flash fry pretty quick when any and every suicidal nut with convictions got their hands on one.
