That is the same reason I don't like learning from videos.

Theres a definite difference...Learning step by step to a voice and visual instructed teacher (in my opinion) is much more clear than having to read something and reread it to really understand it.

This is true <in person>, when you have confidence that the presenter is of high quality and on target. It's not true generally, because in reality the needle/haystack problem. Line of sight is better for parralel processing than serial/ sequential a/v.

If the medium is visual (knitting, a sport, etc) then video is great. But a math lecture is probably better as text, with images/diagrams.

How often are videos remade to fix poor examples? How often is text fixed? (Where's the ever improving video version of Wikipedia?)

IMO it's much worse. It's slower, less knowledge-dense and you can't jump around and learn the things you need the way you like. Reading and re-reading is a feature IMO, not a bug, and videos have all the drawbacks of sitting in the classroom without providing any of the benefits (you can't, say, ask the video for clarification).
