I think an entertaining video, whether from a successful channel or an more amateurish one, is to be taken as entertainment first, and then occasionally as educational when it hits the mark on something, or points to something interesting to dig into deeper. Everything is food for thought, and nothing is to be taken for granted. It doesn't apply just to videos or a certain channel, but also to books, conversations, et cetera.
I agree with Adobe that there is exposure and exposure. The proof of the pudding is in the tasting, but the pudding takes time and effort. It is not a surface exposure to the Cassiopaea material per se that counts, but the reflection, pondering, analysis, observing, meditating, waiting and seeing, that comes with the process that has value.
