Why is this surprising? Nuclear weapons are available. AI has limited real world experience or grasp of the consequences. Nuke 'em seems like the obvious choice --- for something with a grade school mentality. Similar deficits in reasoning are manifested in AI results every day. Let's fire 'em and hire AI seems like the obvious choice --- for someone with a grade school mentality and blinded by greed.
People in the world have limited experience about war.
We're living in a world where doing terrible things with 1000 people with photo/video documentation can get more attention then a million people dying, and the response is still not do whatever it takes so that people don't die.
And now we are at a situation where nuclear escalation has already started (New START was not extended).
It would have been the biggest and most concerning news 80 years ago, but not anymore.
