There is more to learn / do than anyone has time. My kid is supposed to spend an hour on his violin, half an hour an fitness, then some time on chess, then eat - including clean up and/or cook. somehow he needs to fit some free play in too. He doesn't have time for more.
It isn't that he could do that, but what else to give up?
I think for a lot of us that learned linux this way, it was firmly in the "fun time" category. We would have rather been tinkering than most other things.
