One of the ways my mind perceives this is basically as a waste. "Look these two sacks of meat expend nearly the same amount of resources, yet one can't feed itself while the other has positive externalities it dosen't fully capture. The difference being 4 or 5 standard deviations caused by just a few thousand genes. Can't we find a way to fix up the less productive one rather than wasting all that negentropy to build a whole new one out of the same atoms?"

Also I'm generally in favour of letting people improve themselves, it really sucks from an eudaimonic perspective that we can't do anything about such an important aspect of ourselves.

Transhumanism ftw.
