You can't talk to a single person at the party who has an interesting world-view, experience, or education? Isn't that the heart of creating characters? Empathy and experience?
It's fine to not enjoy socializing but acting like it is because you are too creative and smart for everyone else is delusional.
When I go to parties I talk to people about ethics and philosophy and creating music and creativity and cooking, and I trade stories from my past and make jokes.
Acting like watching a lecture on YouTube or reading your thousandths book is somehow superior to talking to living breathing humans because "ideas" is bizarre.
You can do both. Read a lot of books and also socialize.
