Pets are OK sometimes! They do need care and feeding, though; some of us don't see that as chores, instead delightful hobbies. I can definitely see the perspective of "there are better things to do", especially if you don't like those things.
I don't do it because I don't care; I do it because it is super satisfying when it has been boringly running for weeks without me doing anything to keep it up beyond paying the electricity bill, upgrades are extremely predictable, etc.
Boredom is a feature :D
