I think that's the same kind of attitude that makes a lot of people not take global warming seriously.

It's a way to process ideas you don't want to be true, sure, but it's not a sensible or cost-effective way to deal with potential threats.

(And yeah, you can argue AI x-risk isn't a potential threat because it's not real or whatever. That's entirely orthogonal to the "if it's true we're fucked so don't bother" line of argument.)
