Smart people enjoy many different things.

What I listed encompasses many things. You can find lectures on philosophy, biology, anatomy, psychology, physics, Russian literature, religion, history, or whatever topic you're interested in. It's more about depth of information and level of expertise of the presenter vs. "lower rung click bait garbage". Information that demands your full attention for an extended period of time and expects you'll put in effort to engage with it instead of just throwing gimmicks at you to hold a piece of your attention before you click away.

Or if you want to enjoy some slop, then apparently we'll all get plenty of that if the smart people block malware, so no problem.

Generally speaking, something with wide appeal is going to be trash anyway because most people aren't going to want to (or will be unable to) engage with any given topic at more than a superficial level. e.g. compare Andrew Ng's Coursera MOOC to problem sets you can find from his real class at Stanford. It is obvious that he watered down the information hard for Coursera. Almost every class on those MOOC sites is of the "X for non-X majors" variety at best (and that's for people who are motivated enough to self-learn!), which IMO is why it could never truly be disruptive. The "creators" people are talking about are generally this except even more targeted at mass audiences.

Even for people who are interested in "smart" stuff, 100x more people will watch some 10 minute video of surface level discussion with doodles about algebraic geometry[0] and then move onto another 10 minute video vs. putting in the work to engage with 15+ hours of lectures on the subject from a Fields Medalist[1]. World-class researchers provide graduate level educational materials for free (which is awesome), but they could never succeed as "content creators" because any given video will only get ~1k views after years of being up.
