I actually don’t know why people are so sneery about YouTubers. Some of the top YouTubers are millionaires! But even on the lower and medium rungs, it looks like you can make a good, or at least modest living. Certainly a lot of them earn more money than some office workers. As far as I can tell, even moderately successful YouTubers need to be creative, self-reliant, disciplined, come up with new ideas every week etc, as well as developing skills like filming, editing and marketing.
I know some YouTubers stop due to the pressure, and I would absolutely take it seriously if I saw it on someone’s CV.
