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.
I think a better way to think about it is to surround yourself with people you can lift and who lift you. The friend group I usually hang with has tons of back and forth because we all have our own interests. We share common values and some interests but we never run out of things to teach each other. We continue growing together. No one becomes the smartest.
