It kinda sounds like he's suggesting a massive, public, social media platform where the 'good stuff' naturally bubbles up to the top. 'Good stuff', in this case, being what you're interested in and nothing else. And while that would indeed be awesome, it's also pretty obviously a pipe dream. Maybe some breakthrough with AI would help with that, but until then I don't think we have the technology to do that. So, for now humans are in control, and as we all know, the public is filled with marketers, trolls, and other forms of bagbiters that tend to ruin such things when they get big enough. Hakuna matata, I guess.
