Well yeah if you have no hobbies you'll find fewer avenues for meeting people. Taking an interest in people and things they do is a basic requirement if you want to bond with them.

That is the question. I've got no interest in bonding with people, actually. What I desire are intelligent entities to exchange ideas with. I'm an INTP, for what it's worth. Social situations are hard work for me.
