If you're willing to search around and follow suggested videos after you've searched out something definitely helps. Also, I have found so much documentary content, both professional and amateur, that has kept me fascinated by so many different things and different subjects that I've been able to look up and read about and learn about and...no, it's not boring at all.
If you're going to the YouTube front page and following the Trending videos, then yes, it's boring. Also, I wish that all the creators who are doing all these repetitive challenge and tag and reaction videos would allow themselves to stop chasing after viewers and just allow themselves to be weird and fun and themselves, you know? I guess there's a real rush to having more and more and more viewers, and I get caught up in it too, sometimes, but knowing you can make anything you want for almost nothing and have the chance of anyone in the world seeing it is such a powerful thing, so I wish voices were a little less homogenized on the platform.
