I'd have to disagree with the notion of loosing out on "HS experience" and socialization skills. I would argue that these kids wouldn't benefit, and their social skills would remain stunted.

Kids that academically perform at this level typically feel isolated, alone, and ostracized. Because they're academically gifted "nerds", their HS peers bully and tease them unmercifully. Generally these kids remain introverted and strive to be invisible and fly under the radar at school.

Put them in an environment with a couple hundred other nerds, they begin to open up and socialize as they all belong, and feel accepted.

Now, obviously the content of their discussions, debates, and humor would likely seem peculiar to most of us.... however, they would indeed be learning and obtaining social skills.
