I have felt the same for awhile honestly sans the could reitre today. I may have been spoiled though because I used to workin a research lab and then corpo jobs were fine but man the meetings and sudden change in technology for no other reason than its the current fad. I think though its just hard to do something full time for decades and still find it fun at home. One of the things though is as an IT guy I stopped configuring my systems because it was kinda tiresome and so often I had to know how the default was because that is what I would have to help people with. So I limited it to things I just could not live without but did not get to minutia about it. Then I got sorta sick up spinning things up and started going with what was easiest. mac’s when their warranty would just cover anything and then back to windows and even with linux I use easy to setup stuff. I just want it to work and not spend a whole lot on making it work anymore.
