What happened?

I remember how the internet used to be full of upbeat and curious people. Now a lot of sites I used to enjoy are just filled with jaded and depressed losers with a penchant for shitposting. My glasses aren't rose-tinted. The same sites I browse now were much different in the past.
Do you think it's due to the poor economy, or other shitty real world factors? Or is pessimism and behavioral sink merely the result of people spending too much time online?

As the number of people on the internet (due to ease of access), so do the number of jaded and depressed losers with a penchant for shitposting.

Perhaps modern lifestyle has something to do with it too. you're less worried about dying from some horrible disease or where your next meal is coming from so depression is common.
