Also society isn’t going to collapse overnight.

Not if it goes down like you expect it to.

In my experience, the real problems are the ones you weren’t planning for.

Even if we don’t end up nuking each other like we thought we would in the 60s-90s, we could still get a massive asteroid / comet strike with less than a week’s notice. That innocent looking star 23 light years away could have collapsed 22.99 years ago and zap us with a gamma ray burst next week.

More likely: something we don’t even know about comes along and makes life far more challenging than it has been for 100,000 years.
