None of that is related to the parent's comment - even if you prefer them, they're still not searchable or indexed, and rewinding is still a bad experience.
Given that many people (including GP and me) prefer document content (not "text" because you can put interactive tools and diagrams in documents, but not text) and it has all of those advantages, it seems like it's pretty clearly the superior medium.
Plus, human brains are notoriously bad at introspection, so I wouldn't be surprised if you don't actually learn faster from videos, and just prefer them because they're e.g. more engaging.
I don't understand what is meant with not indexable. Many YouTube videos have time stamps embedded in the time line and you can also link a video with a certain timestamp it's only a right click away on desktop.
"Indexable" here means that the content is made accessible in a form such that it can be indexed for searching. You can't search through a YouTube video, and this makes them significantly worse than textual documents that can be.
