Can't speak for others, but I have several channels I follow where this is effectively the format... It's a bit harder at times where it's just a tripod in the corner, and might be more effective with a headband mounted gopro depending on your work. But other than that, just appreciate enough instruction and video to understand how things are being worked on, usually fast forwarding (in the edit) through the more laborious (time consuming) parts.

But I follow such a wide variety of topics from political, to technical, to PC gaming to food (keto, general, other) and home construction or even electronics DIY stuff. I think YouTube has trouble figuring me out... I tend to get fed too much of one thing over time, and have to go into my subscribe list (a few hundred) and start watching from the more recent, or specific channels depending on what I'm in the mood for.
