That must be a somewhat daunting procedure for scientists in the genetic field; creating humans that are much, much smarter than themselves, likely rendering themselves obsolete very quickly.
There'd still be at least a generation before the kids are up to speed. Even if they're of the "finish HS by 12, BS by 13, PhD by 16" types, they still have to accumulate a large amount of knowledge and practice, to actively participate in the science.
And I think science is not a zero sum game.
There's only so much science to go around, so don't go hogging all the discoveries.
