This is your regular reminder that if you are the smartest person in the room, go find another room. You are not going to run out of people or rooms.
@evacide some people mistake this with elitism or something adjacent to it (thus the comments about boring assholes and such...)
But it's actually about finding best spot for learning and bettering yourself. It's great to always be near someone who can teach you something new. It's also great have someone to measure yourself with - to motivate yourself.
To be the smartest person in the room is definition of being stagnant in your growth. And stagnation is a death of mind.
