Finally I realized that non-nerds actually find listening easier than reading.

A lot of nerds listen to podcast. I'd estimate 80% plus of my communication is textual and that includes with family, and I'm a father.

I listen to several hours of podcats per week. Podcasts aren't two way communication. Like text they can be left alone and returned to at will. They can be educational and or entertainment. My favourite podcasts are those which are mostly other people conversing with each other over some debatable ideas. Audiobooks can be good too. I mostly listen to these during routine work, walking or cycling.

seem to prefer e.g. Skype calls over text chats because (to these people) voice chat requires less energy than writing, and feels like just having a normal conversation and thus effortless, whereas writing is something that requires actually thinking about what you say and thus feels much more laborious

I think most people prefer these modes to text and that we're the exception. There is some positive emotional payoff to hearing and seeing friends and loved ones. I've noticed that many people will skype or phone when the want to share positive things, but email or text when the message is a nagative or confrontational one. Lots of breakups happen via text butI imagine very few marriage proposals do.
