Being well-rounded and learning for learning's sake is absolutely something that keeps you growing as a person imo. My take is just that it's worth being critical of what one needs to learn, how much work it would actually take, and whether they really are engaging with the subject in a way that can be called learning rather than information entertainment or some other extremely low level.

With pure knowledge, it's a bit easier to convince yourself that putting in some airpods and listening to a subject while you're actually dividing your attention with the act of driving, is effective "learning". But with things that inherently require more physical engagement, this would seem a bit silly. You can't really watch YouTube video or ask ChatGPT how to kickflip on a skateboard and convince yourself that you've learned much. You need to go to a parking lot and rep out 1000 attempts.

My argument is just that passive digestion of information has an opportunity cost, and unless you're already engaged enough to take it to the streets somehow, you're paying a high opportunity cost whereby those moments could be enjoyed as the periodic gaps they are
