Genetic tinkering gives Nicholas Kristof the willies.
My concern is ... with the possibility that we will irreversibly change what it is to be human. Geneticists have tried to improve apples over the last 50 years, producing larger, prettier species that just aren't as tasty or as interesting as they used to be; it would be a tragedy if we did to humans what we've done to apples.
The fact Nick Kristof worries whether in some dystopic future people will be as tasty as they used to be is much, much too much information about how Nick's mind works. That gives me the willies.
