For me at least it is 100% a hobby. Sure when I’m actually working I’m either running plasma or riverwm basically stock, but it’s genuinly really fun to see how “hollywood hacker” based I can get my desktop to look. It also helps me learn more about interacting with the inner workings of linux since I like to modify things myself instead of using other peoples dots. I even made a shitty terminal application launcher using pure fish cause I wanted to see if I could, and it taught me a ton about .desktop files and binary locations and flags. That information I now use daily building my own applications
