I agree with a lot of stuff said here - caring, or intrinsic motivation, is one of the most powerful attributes you can hire for. There are, however, a plethora of other attributes out there, and restricting your potential hires to the tiny subset of people that are as insanely motivated as yourself seems like a recipe for never hiring anyone and paradoxically never actually solving any problems. Specifically I don't think points 3 and 4 are quite on the money - how much you care is often based on how much you perceive people care about you, and equity can be a pretty big signal of that. Additionally, I think people who care can be quite contentious. Still, a good enough point to talk about. Apparent enthusiasm is one of the best things you can select for, when you see it, and it can make up for a lot of other things that might be lacking.
