Youtube, Twitch, TikTok, Instagram, Hulu, Netflix, etc. appear to firmly support that content is king; at least in some small corner of the internet.

They don't support that content is king, they support that ease of use is king.

Imagine if, to upload a TikTok video, you had to bring it into an editing suite as complex as DaVinci Resolve and tweak all kind of things... add and refine audio tracks... color grade it, etc. It wouldn't have taken off at all.

What all these platforms have in common is that even idiots can use them to make "content"... if you can even call it that.

And maybe even more important, content discovery is king

Either you're very good at discovery or you have to be great at curation/creation
