The quote about the purpose of terms like "content" and "content creator" is spot on. It's the shipping container of the internet, a way to standardize units of things to sell and consume. Call it a necessity of the market, a knock-on effect of Amazon omni-retailers, but it's dehumanizing to reduce all creative effort to indistinguishable units, and strange that so many people take on the mantle willingly.
It's also expedient. Take a subset of YouTubers, they're likely doing different things across multiple disciplines. Video editing, music, education, performance, it's hard to name all those things. Easier to say "artist". Or "content creator". So I don't think it's all due to the machine.
