For what is is worth, I am not an expert in much but I am an expert in a couple of areas frequently brought up in this sub and.... much of what people discuss here is simply not the reality.

Societal collapse in the modern sense is something akin to the breakup of the USSR, or the Balkanization of Yugoslavia. Yes these are big history writing events, but Humanity is not going back to the dark ages.

Yes the economic outlook for someone in the US at least who is ~25 today is objectively worse after accounting for inflation then it was for someone who turned 25 say 40 years ago. However what is not commonly brought up is that someone who turns 25 tomorrow still has a longer life expectancy and higher standards of living than someone who turned 25 40 years ago.

AI is not what people think AI is. A good analog for AI would be the Industrial Revolution. Things that used to be extremely expensive and could only be made by Artisans suddenly became very cheap and available because mass production brought down costs. AI is going to do the same thing but going to do it instead for things that are today created on computers by white collar workers. Things like graphic design, simple software, scheduling meetings, writing help documentation, etc. etc. We are so far from a general AI that can replace a human wholesale that it is really not even worth thinking about.
