This statement is baffling to me.
1. Wikipedia is not wikihow. It is not an aim of wikipedia to teach you how to tie a knot.
2. Youtube does not reward or otherwise provide provenance and incremental improvement.
Look at the revision page for the windsor knot: https://en.wikipedia.org/w/index.php?title=Half-Windsor_knot...
There is no mechanism whatsoever on youtube to incrementally improve a video or understanding of a topic.

Yes there is? You've been able to trim and append end screens for years. Usually when understanding on a topic changes people upload newer videos.
Do you expect the books on your shelf to update every year? What a baffling relationship with media you must have.

I don't think that Wikipedia rewards provenance either? The "reward" seems to be seeing your own beliefs put to text. I suppose that's what you're getting at?
