I mean, curing genetic diseases is good. And it doesn't hurt to make sure your kid is attractive and charismatic. On the other hand, this will absolutely and unequivocally be used for babies with... specific phenotypes associated with wealth or class.

And, worse yet, it inherently encodes a poor tax into the very fiber of a human being that will exacerbate inequality. Something that will only grow as the designer genes become even more effective.

I guess, in the end, the rich will claim to be justified when they call the poor "less human".
