It's actually somewhat amazing how isolated you can get from the average person if you stick to settings & persuits associated with "intellectuals". I recall ended up in a friend group of 8 people once that included 3 geniuses.

Sometimes you really have to take a step back and realise that you're not as normal as you feel. You can spend your time on hackernews feeling very insecure and then apply 5% of what people talk about here and then the average person will treat you like you invented fire.
