As I understand it, we use different regions of our brain for interacting with tools, people, animals, etc. I enjoy using the tool part of my brain when computing. It feels "quieter" and contemplative. It feels like I am doing something, not like I am asking an assistant to do the work on my behalf.
I like social interaction a lot too, but as an introvert, it's kind of draining. I would have to leave computing if using a computer felt like being in an intense conversation with a computer-person all day. Even if the conversation is pleasant and fulfilling, it would be too much social interaction.
