Knowing a lot used to be attractive too, before the septic cavalcade of reddit reduced us to wordcels and the 'actually' meme. The continued pursuit of knowledge for me has been a much more private matter in this last decade of the unravelling academic institutions I once called home.
There's tact to be deployed when you know a lot.
People are less frustrated with the actually meme if it's insightful and not some pedantry.
It's all about context. Everybody likes someone who has well informed answers to questions they ask. Nobody likes someone who frequently injects answers to questions nobody asked. Knowing a lot is attractive, but being a know-it-all is unattractive. The wisdom to know the difference between the two is a different kind of skill than knowing a lot of things.
