Segregating gifted children in with the regular population will one day soon be seen as child abuse.

It has profound negative effects on the child, and leads to really terrible outcomes like drug abuse and absenteeism.

We have a lot of evidence that shows this. What you posit above amounts to exploiting the gifted child to benefit the needs of the other children. Gifted children are very open to being exploited by peers and teachers in the regular classroom.

It's wrong, and a detriment to the children and society.
