Most online debate is actively harmful to our thinking. Every hour spent arguing on Twitter is an hour we could have spent reading a book, writing an essay, or having a genuine discussion in a better environment.
The Internet promised us a marketplace of ideas. Instead, we built a gladiatorial arena where ideas go to die—time to find better places to think.
It’s framed as that this is about the whole internet, but seems like they are mostly talking about Twitter culture.
Mostly, although I think it applies more broadly to varying degrees. Even to Mastodon (although without the Algorithmic amplification aspect).
