> As a professional YouTuber

Well, there's your problem.

You want the numbers that come from mass consumption, which means catering to the lowest common denominator thus producing shit with gold plating while then complain the gold plating is bloody expensive.

Some people just are knowledgeable and want to share with the rest of us mortals like say someone like Terrence Tao. Putting someone like him on "YouTube" is a goddamn travesty. We need an alternative and yes, you won't make money and no, it's not for you then.
