The internet has created the ability for any given subculture to discover instant validation and reinforce their beliefs into a tribe, which further solidifies and extremifies those beliefs.
It's a psychological power almost equivalent to a nuclear reaction: beliefs and ideas that might have naturally died out pre-internet are instead amplified and spread, and dug deeper into peoples' minds.
This is a critical time to be in tech, but not for the growth: for the need to design solutions to that problem. Censorship is a primitive attempt at stopping this psychological nuclear reaction; people are finding ways around it. We need a bigger, better solution to the reaction, lest society destroy itself through unfettered tribalism.
