I feel like that was addressed, in bits and pieces. If you're worried about your kid ending up "abnormal" or "out of place"... well, yeah, they will. But the author (and myself) have no problem with "abnormal". "Normal" is not necessarily good. He does say that he's worried about boredom (and again, I agree), but that is much more easily fixed by looking for teachers or special programs that can cater to the child's needs, maybe skipping grades... or, if that fails, continuing to enrich your child's education yourself.
