>Isaac newton was a sperging virgin, yet he is probably one of the most known scientists in history nowHe was a bit of an exception. There are many well-known mathematicians, like Cardano, Leibniz, the Bernoullis, Euler, Riemann, and Poincaré who had good social lives and who corresponded with people either for the sake of sharing their knowledge, posing problems/puzzles, or merely for the sake of socializing and conversing about trivial stuff. Leibniz famously wrote a series of letters to a German princess talking about philosophy. Also, John von Neumann was known for being great at telling jokes in all of the languages he knew (Yiddish, Hungarian, German, and English), and had no problems talking to anyone from children to fully-grown men.
People who achieve some level of success or notoriety rarely tend to be capable of doing only one thing right and otherwise being completely dysfunctional. More often than not, they tend to be somewhat competent at basic tasks and can fend for themselves for the most part, but have a particular strength or remarkable focus on something. You can find shut-in NEETs who are very good at drawing or making music, but you probably won't find a Caravaggio, a Raphael, a Dante, or a Whitman in groups composed of shut-in NEETs. People who don't care for the world tend not to be very good at understanding it.
