There were lots of doomsayers in history that weren’t wrong I’d the point, yes those of us talking have ancestors that got through terrible times (some of them predicted some not), that wiped out large swaths of people and survived but there are lots of other terrible outcomes that are terrible and unwelcome.

My grandfather lived through ww2 m, which was a HEAVILY predicted event filled with doomsaying right after WW1, and it was a point of debate.

It wasn’t a pleasant experience, lots of people didn’t make it and entire communities were destroyed, for them it was the end.
