The man who mistook his wife for the hat: Do you think separating the savant twin was the right thing to do?

I read the book a few months ago, and it was really perspective-changing. All the stories are filled with new insights and make you think about the wonders of the brain.

But I keep wondering about the savant twins. Was it right to separate them? The world of numbers they built around themselves was such a big part of who they were. I do understand that they needed to adapt to society on their own, but still! It is sad that they had to lose so much of themselves just to conform to the idea of "normal" when the disorder itself was such a big part of their identity.
