I am very excited for NixOS, for me. In the professional IT sphere, outside of DevOps, this is so far away it is depressing. I spend my weekends with QubesOS, NixOS, and maybe in the future GuixSD and SubgraphOS as my therapy.
I have started to look into a career transition into DevOps (please do not laugh, feel free to downvote) not because of how cool it looks or the increasing culture around it, but I need a break from the mainstream of throw everything and anything on the wall until it sticks without rigor, or your time is cheap automation is a very, very low priority since we pay you to do the tasks we dislike as more serious engineers (who also build some systems with checklists).
