Honestly I don't see the thirty something generation ever giving up video games. They've been a part of our entire lives at this point. Once we're old, it will be a case where no generation has ever been without video games in some capacity.
Am 43. Grew up playing games. Not planning on stopping any time soon. Went through the 'I should be doing something better with my time' phase briefly, about ten years ago. Realized it was anxiety driven, not rational. Having fun is an intrinsic part of being human, and cannot be skipped without genuine mental health consequences.
When I get downtime it's pretty much just turned in to playing games or watching TV - I barely have time when I feel motivated enough to start learning something new anymore. I taught myself almost everything I know about programming in downtime during my teenage and college years, but that sort of highly motivated downtime hasn't carried over so well now that so much of my time is occupied automatically.
I think you're right and having actual downtime when you're doing something relaxing is a very good thing, but I can't shake the feeling I should be accomplishing more.
I guess I'm just sort of disappointed that all my most motivated times seem to have sunk into other activities and now I don't get them to learn on my own. I don't know what to do about it.
EDIT: You know, I don't know anyone else who feels obliged to spend their free time in some sort of "productive" way except developers.
Maybe I should just ignore this whole thing and accept that development has for the most part went from a hobby to a job for me and that's okay. Spending time with friends and gaming in my free time are probably more relaxing and improve my overall happiness more than forced productivity would. Optimizing happiness is probably a better idea than optimizing productivity.
Eugh, I don't know, I keep bouncing back and forth on this one in my head.
