Soon it will be a sin for parents to have a child which carries the heavy burden of genetic disease.
But not yet please. I have two issues:
First, We still don't know enough to prevent unintended consquences or complications. We could edit-out one problem and accidently edit-in another.But one day, in the not-so-distant future, perhaps another generation or two, yes - definately. We should erradicate all heritable diseases.
The second thing, I would draw the line between correcting errors/curing diseases and between creating eugenic supermen. Please no Gattica-style selection of socially prefered traits to create a dis/u/topia of ubermenchen and untermenchen.
The quote was from Bob Edwards who until a few years ago was host of NPR Morning Edition. (BTW, the quotes in the game were all narrated by Leonard Nimoy, which was super cool)
