If you're interpreting "super-smart" to mean always right, or at least reasonable, and thus never severely wrong-headed, I think you're correct that no one like that exists, but it seems like a rather comic bookish idea of super-smartness.
Also, I have no idea how good your judgment is about whether what you call brain-hurtful is actually ideas I'd think were egregiously wrong.
I think there are a lot of folks smart enough to be special people-- those who come up with worthwhile insights frequently.
And even if it's just a matter of generating lots of ideas and then publishing the best, recognizing the best is a worthwhile skill. It's conceivable that idea-generation and idea-recognizing are done by two people who together give the impression of one person who's smarter than either of them.
To whom it may concern:
