Humans are social creatures by nature. Evolution had a hand in that. Those who worked together, survived. Those who didn't, died.
I'm not sure sociopathy is at all associated with an immunity to lonlyness. That being said, I consider myself a bit special in that I seem to prefer my own company over that of others. I think it's due to the fact that I've spent so much time in front of my computer.
The computer is constantly engaging. There is always something to do. Always some way to be distracted. The world's information is at your finger-tips.
The only time I find logical reason to socialize with anyone for any purpose outside of businss is for the sake of socializing itself. For the sake of talking with another Human. At the same time I see how wasteful it can be.
I find that it's quite easy to fill the hole that lonliness can bring. I do my best to build relationships with my business clients. This is very good for business, but it also serves as a pretext for socialzing. Additionally, this forum isn't a bad place to socialize. The long-time members of this community know eachother quite well, and even the members whom I dislike-- I find myself fond of simply becasue of the history we have together.
When I consider my future, and what I'd like, I see myself high up in a sky scraper. Alone with my computer infront of a huge bay window overlooking the city, or perhaps a harbor. The people I see around me are tutors, cooks, and maids. Other than that, business partners.
I don't mind the presence of staff so much becasue they don't require effort. I can ask them to leave, and they will do so without question. I can set strict rules to distance myself, and only talk to them when I'm interesting in talking, and not the other way. I don't have to agree with their oppinions or ideas.
That's not to say I'm not a polite person. The truth is that no-one in real life thinks I'm rude. I understand others, and I am careful not to make people feel rejected, or ignored. This requires a lot of energy though, and is likely partially the reason why socializing exhausts me.
One example I recall was a couple months ago in China. I had 1 friend who was Irish. Another was Italian. One night both of them were drunk, and we were having a conversation. Both wanted to speak... simple for the sake of speaking, and who ever I looked at would feel as if they were being listened to, and would then speak. Which ever person I didn't look at would feel ignored, and cease to speak. Perhaps people don't notice this phonemena, but I see it everywhere I go, and the energy required to make sure everyone feels respected and heard just isn't worth the time. Mostly because most Humans are very stupid.
With web-technology, Humans no longer are Gurus. A computer will almost always be smarter than a Human, and this makes it difficult to care very much about the facts they are giving. It still stands that their oppinions can matter, and creativty is still of value, but it doesn't change the fact that socializing isn't as value as it once was. I'd go so far as to argue that extroverts, outside of politicians, are at a disadvantage with the new meta the internet and web-technology are moving society into.
Welcome to the forum by the way. You will find an array of personalities here. Some high-functioning sociopaths. Some low-functioning. Some empaths, and so on. It's best not to lump everyone into a category, but instead learn about each person on a case-by-case basis, and try to understand the reason they have became who they are. It's very fascinating to me, and hopefully for you as well.
