idk if ~1k views can be called "no audience". Of course it's nothing you can earn money with, but it's still ~1k people having some fun and totaling ~83 hours of watch time. So even if he hated making his videos, if they took less than 83 hours per video (which I think is very likely) this is a positive impact on the world. If he liked making them then it's already positive anyway.

I don't think it's really important that something isn't "mainstream", the only thing I think is important is the effect it has on the people that do get in contact with it.
