Also there is a difference between studying and reflecting on something outside of work, and actually practicing outside of work.

Do I want my surgeon to be studying the latest techniques outside of his work? YES

Do I need a surgeon who dissects animals and removes tumors at home as a hobby on weekends? NO

Is there such a distinction in programming? Plenty of people use side projects as a way to test out new languages, tools, etc. It's widely held that learning programming in general is easiest if you have something you're trying to build. Are there people just reading a "React for dummies" book and coming away comfortable with it?
