I can be a hobby dilettante, so there’s a lot I could list.

Technology and personal computers is probably the biggest one. I used to work in IT and as a hobby had a few computers at home running different flavors of linux for different purposes. I was a big technology enthusiast in general. These days I maintain a basic level of knowledge and awareness because I feel like I have to. I would happily give it all up if I could.

I also follow Magic the Gathering developments despite not buying cards in decades and it’s been about a year since I played Arena (the free online version of MTG). The rules and card interactions are still really interesting, but I just can’t be bothered to play. I’ve thought more than once about applying to be a judge for MTG tournaments.
