I always wondered about the economics of YouTube. I know it's nowhere near as easy as people think it is.

Even if your costs are low, you have to keep pumping out videos to stay relevant. And it must feel pretty bad for your boss to be a faceless algorithm that can change on a whim.

That being said, I really admire what a lot of YouTubers do, especially channels like 3 blue 1 brown, and think it's one of the most promising avenues for education. I've thought multiple of times of doing something similar myself.
