No... that sounds an awful lot like revisionist history trying to force a utopian ideal where none exists. If anything, the advent of the Internet and social media in particular has made us more tribal, not less.

The majority of the Internet is geared towards feeding the hedonistic treadmill of porn, cat pictures, selling things, influencer chasing, faking happiness on Instagram and trolling political sides on X or Blue sky.

We aren't better people as a result.
