There's isn't a platonic ideal of social media to argue for/against though. Pandora's box has been opened and we can't unopen it. If Facebook magically disappeared tomorrow, people would still take their phone-computer out of their pockets and send messages, thoughts, pictures, videos to their friends and family. Socializing through multimedia technologies. Where there are platforms that don't have the same problems as Facebook, (but also don't have the same reach as Facebook), what is actually inherent to social media, and what is because it's built on top of late-stage capitalism? Hate speech and radicalization hit an inflection point in the 1940s, hopefully we can avoid the same in the 2040s.
