"Everyone doesn't have to know everything" is a great sentiment.

I often think about https://xkcd.com/1053/ and how it's broadly misinterpreted: the point isn't that we should accelerate the education of everyone (at least on things of non-vital import), the point is that it's mutually fun to actually have the experience of sharing with a single person or a small community. And of course, as the XKCD says, it's important to do this freely and without judging the learner... but that freedom to share often exists precisely because the knowledge remains obscure.

If we don't like the commodification of the "inside joke" into a mere vehicle for advertising, as so much of culture in the age of algorithmic video feeds is becoming... then we need to let spaces and knowledge be obscure sometimes!
