I can't quite tell if it's because I like programming more, or if it's because as I get older, I have trouble justifying stuff that I know won't help with monetary or intellectual fulfillment.
I don't think it really has anything to do with recognizing something as being artificial happiness. It just has to do with change. There are speedrunners who code for a living, come home and compete for the fastest times on any number of games, spend their time attending things like AGDQ or contributing to the various micro communities within the scene.
I think people tend to fall into either passive or proactive mindsets for their hobbies. And it's a sort of spectrum over time influenced by the communities you belong to. If you're part of a community for your hobby, then you get more out of it due to community momentum. Sort of like the person who plays games to relax after work, versus the person participating in a speedrunning community for a specific game.
I would say that I don't get addicted like I used to when I was a teen. I've often attributed that to realizing it was a destructive behavior and learning from it though. If I had more time, I would probably play more though.
There are already video game systems in nursing homes. They don't have much 3d shooters, but wii bowling is popular (or it was 2 years ago, since my grandma died I haven't had reason to visit).
I do enjoy my job, but I'd get burnt out doing it much more than I do.

I even try to play games occasionally because the idea is still somewhere in my brain that it would be fun and relaxing. I even usually overbuild my workstations to handle AAA games thinking I might just play one this year.
But they just don't hold my interest anymore. I don't really know why. That endorphin hit when playing just doesn't happen like it used to.
