The Eugenic Bogeyman
It looks as though some scientists in China have produced two infants from ova edited using Crispr. The objective was to disable a gene associated with vulnerability to AIDS. A good deal of the commentary on the report is negative, with talk of eugenics and risking the human gene pool and such. I find it hard to see much basis for such concern. There are obviously risks which the parents should have been, it is claimed were, informed of, but then there are risks to producing a child by the usual technology as well.
I am particularly unsympathetic with the way in which “eugenics” is used as a bogey word, since it confuses two quite different things. Eugenics in the sense of some people deciding what children other people will have is a bad thing, especially when it involves some people deciding that other people will not be permitted to have children. Eugenics in the sense of couples trying to improve the quality of the children they have seems like a reasonable and unobjectionable activity. At the individual level it happens every time someone includes, in the choice of whom to marry, the consideration of what sort of children the proposed spouse will produce.
My favorite version of eugenics is the one described in an early Heinlein novel (Beyond This Horizon). It was a technology that let a couple select on both egg and sperm, thus choosing, among the children they could have, which ones they did have.
Comments? Any readers inclined to defend the arguments against this sort of technology?
