Watching someone cut a dovetail by hand is a lot more interesting now that I know from experience how hard it is. And maybe I'll learn a trick to make my next ones better.
I'm not surprised. They are very hard to make correctly and not that much better than other options that are easier to do. they are a "holy grail" of wood working skill for a reason. I've done a dozen in my life and the best is so awful I want to burn an otherwise nice creation to hide the evidence.
If I want to do my hobby, I need to make time for it, whereas if I want to watch videos about my hobby, I can do it on the toilet. It turns out it's a lot easier to watch than make time for a hobby, hence why I do more of it.
If I didn't have to work, I'd spend more time doing my hobby. But I do, and I have kids, so hobby time is quite limited.
