Comment The cozy catastrophe fantasy (Score 1) 90
... is a movie trope where everyone in the world has perished, except for the protagonist, who is now free to roam the world unmolested, help himself to any of the remaining resources available, do whatever he/she wants, etc.
The fantasy part is the idea that the catastrophe will get rid of all the people you don't care about, freeing up their resources for your own use, while sparing you and the people and resources that you do care about.
The people in this article can be blasé about AI killing humanity because at some level they think that they and what's important to them will be spared. Most likely, they think their wealth will save them. If and when they find out that they will suffer and die as well, their acceptance of the idea will evaporate quickly.
