Let's be honest: way more people than we would like to admit gravitate towards junk content on their own, most of the time.
Celebrity gossip and conspiracies, reactionary politics and pseudo-science.

There is a ton and a half of extraordinary educational content on places like YouTube. Say you start watching videos from the PBS Spacetime channel, then start watching what the algorithm throws at you. Pretty soon you'll be getting things like Cambridge physics lectures on your feed. Then suddenly videos about mathematical equations start appearing, another rabbit hole opening up before your eyes.

The algorithm is an incredibly powerful tool, and just like a knife or a blowtorch, it can be mishandled and/or abused.

So you give people the tool, people start inputting shit into the tool, and when shit comes out the other end, it's all about "oh look... it's the fault of capitalism!"

Maybe capitalism seems mediocre because people are mediocre.
They rant about how there's no good options, you give them a good option, they stare at it blankly for a second before turning their backs on it, to keep on ranting about how there are no good options, and how it's exclusively the fault of some pig in a suit in New York City, or some librul mooslem-lovin' gay commie bastard from Hollywood.
