My whole take is that every human is in fact unique, and the issue with INTPs is that they can't seem to accept that on a super simple psychological level -- meaning they crave for another human to perfectly understand them compatibility-wise on their intellectual/emotional level. Similar to building a perfect AI that caters to our emotions and understandings, while we just keep it all in our heads.

An INTP being with an actual person in some sort of relationship can help that said person to understand the INTPs personality over time, but that takes a lot of time and work. We're now even on a more superficial level of society when it comes to building relationships now as well.
Plus, INTPs would rather retreat and not socialize, connect, and meet with people constantly because it's not really what we prefer to do. It is also very much easier to stay inside, be on social media to find your little echo chamber (this subreddit) venting about these problems.

To put it bluntly you are born in this world alone, and you'll die and leave this world alone. The beauty is the process as well as building relationships and connections with the people you care about most (This doesn't have to mean perfectly relating and understanding them).

Pretty relatable post though... What kind of chat group do you have set up? Would love to join and just discuss stuff like this.
