Many were desensitized by the early, totally unmoderated internet.

I’m really confused what this could be referring to.

Because the folks who’ve been around the longest and remember the early days of the Internet are currently in utter dismay over how their fun international sandbox has become a Black Mirror-esque horror show, while everyone else seems to just shrug and obediently upload their face scans so they can watch AI videos of uncanny-valley cats playing cruel pranks on facsimiles of political figures in-between unskippable ads for applying to be an ICE agent under promises that it’ll be like COD but in your own backyard with living, breathing brown people.

I’m also clueless and don’t understand what the OP is talking about - who is having a mental breakdown and why? And aren’t the millennials who are the only tech and internet literate generation exactly the people having a mental breakdown over the way the internet is going? I’m so confused, I need more context.
