I reckon discussion used to be moderated by the elites. Ideas too radical (anti-vaxx, etc) would not have received widespread coverage, people who are too extreme would not either. Editors and network owners could apply prejudice and moderation. This is all gone now, instead we have people flocking into extremes in endless feedback loops (some intentional, some psychological, some algorithmic). I'm sure new mechanisms for self moderation will grow out of this. The generation growing into these platforms as their only known reality will need to take the lead and set up new rules which would allow society to keep existing. This is a work in progress.
