>What do you do if you have difficulty caring about most people you might talk to?
If it's inherent to your nature to be like that, then I would honestly say, find a way to get autismbux (if you need to), or look at the top of the pyramid of innovation, and get yourself there. If things are being replaced by automation, the spots left for people are in 2 places: the caring professions you mentioned, but also in the invention and application of automated systems.
If you feel like it's not inherent in your nature to have trouble caring about people, your third option is to question how you can change this part of yourself so that a job that involves social interaction is more plausible for you.
