I'm not sure it's generational. I've always encountered developers who prefer to learn from people rather than words. I think the difference here is that now that YouTube has come along these developers are catered to more, so the people who prefer to learn this way have a better choice. I don't really see any advantage to video over text / rich documents for learning development topics, and I see several downsides. But perhaps I'm biased, because I'm like you and very strongly prefer words. I expect improvements to the technology will help alleviate some of the downsides to video in the long run as well. Are there any video platforms widely used for developers that let you do a full-text search over the transcript for code and then jump to a point from a list of results? Because that at the very least is a dealbreaker for me.
