I 100% agree that for repairing stuff and sports related topics that videos help a lot. When I used to work on my car it was helpful to see how things were typically done and then when I read the repair manual it filled in the gaps of knowledge because I knew the way it is usually done. When I was doing a lot of power lifting it was really helpful to learn from video how to do lifts safely and correctly. Then as I went from lifting to cycling and eventually to endurance running it provided me a way of learning good form by watching a real human explain and demonstrate instead of just imitating what I see in real life.
Sometimes though technological tutorials/videos end up being this 80% junk to 20% treasure ratio for me. However, that 20% is stuff I have watched very intently and actually learned something.
For me it depends on my mood. If I am in a rush and I quickly need to find how to do something, it can be hard to find Youtubers who are concise. But other times I want to hear everything there is to know about the process.
As a good example, across the PC building space, there are two Youtubers who actually refer to each other both Gamers Nexus and JayzTwoCents. In Jayz videos he knows he provides a summary so will refer you to GN for more in-depth detailed content.
However, for cooking technique and building/home-repair/car-repair, videos are a game changer. Simply amazing. Actually, that goes for sports stuff, too. I find reading about all those things nearly worthless, and watching someone do it while explaining, a much better use of my time.
