I don't think that there's nearly as much adaptation as there is just people getting used to watching video content and liking it more. That is, greater enjoyment, but not greater comprehension.
I suspect that nearly everyone who thinks that they "learn better from videos" just enjoys the videos more (which affects how well they perceive their own learning efficiency - humans are notoriously bad at self-assessment especially in the cognitive realm) and/or has attention issues that are mitigated by the more engaging nature of a video.
I actually have a pet hypothesis that it has something to do with imagination. I'd be curious if anyone has studied the effects of visual media on imagination and how it impacts kids ability to take written content and understanding it versus the same with visual content. I have a suspicion that before the prevalence of visual media it was even more critical to have an active imagination to be able to synthesis written content and that we've lost a bit of that in younger generations as we've moved toward a reliance on visual learning. I have nothing to back any of this up of course just something i've thought about when reflecting on myself.
Imagination is a "mental muscle" that must atrophy with disuse.

> For me video talking about code is slow, unsearchable, unskimmable. I cannot easily go back to more difficult parts and reread (watch) them at my own pace. I cannot use them as a quick reference. Even my photographic memory doesn't work with videos, there's just something more powerful with black on white words and formulas.
You also can't copy/paste code, and if your vision isn't perfect/the code isn't zoomed enough, you have to use a whole screen for the video.
Then I learned some more, which got me to the stage where I knew what the hell he was on about, and now I love him. Information at its maximum density.
For things I'm already familiar with, usually calling the man page is enough.
Take food, for example. I have books that go into great detail about how to make bread. Each ingredient (of which there are only four) are discussed in detail. The history of bread and its influence on culture is covered. But when it comes to kneading dough, nothing beats watching someone do it. Even the best book in the world can't replace that.
I learn a lot from watching others work. When I watch videos I'm learning more from what they don't talk about than what they do talk about. I think it requires being selective. There are some videos of really talented and skilled people out there who might not be great communicators. These are treasure. On the other hand, there are shiny videos with attractive presenters filled with trivial fluff you could have gleaned from one page of a text book. Like with anything, you just have to learn what's worth your time and what isn't.
So videos with slides, and notes, and tutorials/practice all can help. It does for me anyway.

Also completely agree about youtuber credibility. Being easy going, with good lighting, nice looks and neat surroundings makes them sound authoritative on the subject they talk about, especially to the newcomer ears, without any real backing.
