QAnon has no platform available. Hell, maybe we still have blogs but you aren't plastered echo-chamber friendly messages you have to actually search for stuff to read or maybe go to a phpbb forum.
Trump without Twitter, QAnon, 4Chan would've probably played out differently. Without a way for society to constantly feed his narcissism would he have been so anti-mask - would anti-science even be so big if there weren't echo-chambers re-inforcing this?
That's just social media itself. It's literally poisoned our society as much as a social credit score in China probably has there among relationships. Piss someone off and now you're an enemy combatant and can't travel.
I think tech can also fix a lot, but it depends how we use it and what we do with it. I hope we can science our way out of Global Warming but I'm not very optimistic about us surviving into 2100s.
