I am 45 and I almost only listen to new music. I have almost a 1000 CDs from the 90s and early 00s (all ripped to FLAC), but I find myself listening to new music because there is so much fantastic new music out there and it is so easy to access. For a music fan it really is the golden age (not so much for the musicians).
As for learning new programming skills I still enjoy it, but I think this is because for me languages/frameworks/algorithms are just tools. The real fun is in using the right tool to solve a complex problem.
Same here. I basically get bored with most music fairly quickly so I'm always looking for something new. Most of my high-school friends are still listening to the same music from the 80's and 90's though!
