YouTube I'd grant you, not Shorts/Reels/TikTok - the format of the media simply isn't amenable to output matching longer-form work, no matter how much gets produced. To me that reads akin to "there are so many tweets that for any criteria a [set of tweets] demonstrate quality similar to any long-form written piece."
If a quote can be profound, so can a short.

why not? seems like a tautology. what's a robust set of criteria we can use the evaluate this objectively. I bet you TikTok will win. mind you I am not saying the average TikTok is good, just that there's probably some set of videos that that are of comparable quality than something put together over a longer period of time like a novel.
