To adapt the well known observation: “just because I’m paranoid doesn’t mean they aren’t out to get me”:
Just because people have always believed it’s the end times doesn’t mean it isn’t the end times!
In fact I think it’s probably overdetermined in the sense that there are multiple threats that could end humanity in the 21st century and it’s just a matter of what gets us first: nuclear war, ecological disaster in the form of species extinction (insects in particular) and habitat collapse, climate change, artificial intelligence, deadly pandemics. Personally I think artificial intelligence is the greatest and most imminent threat, though nuclear war could take us any time, and if neither of those two materialise then ecological disaster or a deadly pandemic will catch up with us sooner or later.
All of which has got people thinking more about simulations, aliens, and even God. If there is a God will he step in before humans finish themselves off entirely? Are we at this interesting point in history for a reason? Whatever that might mean. I think they are reasonable questions to ponder.
