I would take it even farther than that and say that people vastly overestimate the time it takes to get good at most things. It might take 10,000 hours (or more) to be considered an expert pianist, but you could spend a tenth that much time getting good enough to impress everyone you know with a few songs at parties, and with just 50 hours of practice, you'll be better at the piano than basically everyone you know (you might not be "good", but a lot of people are also easily impressed, if impressing people is your thing.)

I think this is true of practically everything that we don't personally make a profession of. A few tens of hours doing carpentry, fiddling with plumbing, or hooking up electronics, and you'll seem super handy to someone with no experience. What passes for expert-level in a lot of arenas is more like what an actual expert would consider passing familiarity, but passing familiarity is enough to feel good and to be really helpful to your community in a lot of circumstances.

I agree completely about hobbies. I think I read somewhere long ago that we ended up with a zillion apps for ordering food because that's the kind of thing that college kids think about. If we all learn a lot more about a lot of things, we'll end up with a much more interesting tech-ecosystem.
