Where are we going, and where do we want to go, genetically speaking?
Of all the politically correct stances, the genetic unimprovability of humanity is perhaps the most inviolable. Even while we work daily, even feverishly, to improve other aspects of our material and cultural existence, our biology remains an ethical red zone, where nothing can be done and no infringement placed on individual replication. As a response to the abuse of eugenics in the 20th century, and to the deep philosophical problems involved, this is understandable. But it does not do justice to the underlying science.
Eugenics are a real issue, have been a real issue, and will continue to be a real issue. Genetic modification techniques will come to be applied on humans, and the rich will get it first. Looking away from these realities because they are uncomfortable is weakness.
