I think the biggest issue is with the regularity of having to post things and be a "consistent product". In the era of broadcast TV this was done season by season, with the bulk of the stress coming from avoiding cancellation. You got your slot for weeknights, or once a week in prime time, and that was it. The process was self-limiting and distributed the stress around - not to the point where everyone was relaxing, but it allowed for some breaks. In the open-platforms era it's all self-imposed, so the standards are allowed to creep upwards to extremes.

I started on a video essay project which will go on Youtube and can see this hitting me already. There are some incredibly productive folks out there who have a dedicated staff to add the magic of editing and audiovisual effects. I will be happy just to get my audio sounding OK and to have something resembling visual style.

Regardless, I have confidence in what I'm doing because I have a clear direction and intent with the content with relatively modest goals(a portfolio building career move). Optimization for the short term popularity metric guarantees that you end up competing in a world of formulaic "man talks into camera", "man plays video game", "man reviews product", "man lives everyday life" type content. And while I could see myself doing some of those, for fun or experimentation, I wouldn't want to become someone reliant on it. It helps to have a few different things going on.
