In Carl Sagan's Cosmos, he talks about how many advanced civilizations could be out there capable of radio astronomy, and how as in our own experience, we have the capability to wipe out own civilization, so that would also be a factor in other advanced civilizations and could act as a limiting factor. There are many such factors other than nuclear destruction that could impact all functioning of an advanced society, rendering it nonviable.
The idea has nothing to do with "doom scrolling". Go watch some Cosmos...
Of course it's related to your doom scrolling-provided depression. You think every single civilization is going to wipe itself out? You think most will? You think half will? Why, because humans are mean?
I've seen Cosmos. It's not a counter to this argument in any way.
