Re posting it with the correct link, sorry.
I read this article the other day and I think it helps explain why some people can't imagine a world in which humanity ends or is seriously threatened. Basically it talks about that we lived through the initial global warming (sea level rises), nuclear threat, ozone hole, pandemics etc and we managed to survive those. Therefore any future threats can be instantly dismissed as false because all previous threats did not eventuate.
But we are only living in this timeline where those threats didn't happen. In any version of Earth that they did happen we wouldn't be on Reddit right now talking about it. Future threats are real, just because we managed to get lucky in the past.
And also the reason we managed to get lucky was because people took them seriously and worked tireless to avoid them. But now with the current attitude we aren't doing that which makes these future threats like AI even more scary.
Anyway I can't explain it as well but here is the article.
