I wonder if it's the technology or if it's just getting older. Not a musician, but I used to do all sorts of creative stuff as a bored 13 year old. Programming, painting, coming up with board games, experimenting in the basement. Now that I'm an adult, I blow 1/2 my waking hours at work, then there's the family that wants to go hiking next weekend, and a kid to play with, and paying bills, and doing taxes, and cleaning the house, and mowing the lawn, and fixing the leaking sink, and being on boards and committees in the community, and on and on. I can maybe carve out an hour a week to do something creative, and by that time I just want to down a six pack and catch up on sleep.
I think today's technology does stifle creativity as well, though. Music was meant to be spontaneous and improvised, which is very easy to do with older synths and acoustic instruments. Production in a modern DAW is anything but that, and it's way less tactile.
