I concur.

It sounds like the coworkers are perhaps more knowledgeable in some areas, rather than necessarily having higher IQ's.

And getting to work with people who are more knowledgeable than you is exactly where you want to be.

Never be the smartest person in the room (unless I guess if you are trying to sell or buy something).

IQ doesn't mean everything. Some people with very high IQs are terrible at making use of them. Theoretical smarts aren't always as practical as practical smarts.
