Yes. you just can't see results because the business sustainability curve is so high you need to climb it like a mountain. Growing a youtube channel that people don't just watch in passing and has subscribers is no easier than growing a website (I had a chat with efialtis the other day on telegram about the growing part).

And sometimes you suffer setbacks like a youtube copystrike or maybe they decide to pull some of your videos. Don't forget these are centralized services that can kick you off their platform if they want. Recently I was kicked off AWS for the second time along so my in-development business API has to find a new home.
