That's true but it's just difficult to find people whose perspectives are valuable. At some point I decided to be more approachable in order to have more friends. While the skills I gained from that are useful, I also discovered that most people are just not worth my time and energy.
Having said that, I absolutely love the moments when I'm talking to someone and the other person tells me something that is indeed valuable. That's why I do put effort into maintaining friendships with people who aren't NPCs.
It’s a mistake to consider other people as something other than autonomous agents in their own lives - it’s popular to conceive of other people as somehow not making decisions; frequently this indicates they’re making decisions by different criteria and using different information than you. This is what I mean about perspectives you don’t have access to - I won’t say there aren’t people who fundamentally are not making real decisions in their lives, but that’s fairly rare, and if someone’s making choices that don’t make sense to you, there’s often a reason you don’t see. Again, you may make different choices than them, but actually truly understanding why they make the choices that they do - to the degree that you can understand and describe to someone else their worldview, constraints, and goals - improves your understanding of the world and your ability to accurately model, predict, and explain it.
