More succinctly:

The Nash equilibrium of public discourse on social media is extremism and polarization ...

... because for each individual, the way to get more clicks and influence is by becoming more extreme and polarizing.

Sigh.

Exactly, so about that, there's good news and bad news. Epistemic and mean field game theory is eventually going to be well understood stuff and define better alternatives very, very specifically. After we understand our past completely AND can predict our future, we'll know exactly what to fix and how, but unfortunately nothing whatsoever will change anyway. Probably someone will weaponize it to actually make things worse! Cold comfort to be sure, but I personally will still sleep easier after I know exactly why we are doomed.

Idk, I’m a big critic of social media (don’t use any but hacker news). Really do think it has lots and lots of problems.

But what’s polarized me isnt that. It’s just reading regular news and caring about the world.
