Walter Isaacson–Should the Rich Be Allowed to Buy the Best Genes?

The French Quarter, where we live [in New Orleans], is hopping that weekend. There is a naked bicycle race that is intended (oddly enough) to promote traffic safety. There is one of many parades and second lines to celebrate the life of Mac Rebennack Jr., the funk musician known as Dr. John. There is also the gay-pride parade and related block parties. And coexisting quite happily is the French Market Creole Tomato Festival, featuring truck farmers and cooks showing off the many varieties of succulent non-genetically modified local tomatoes.

From my balcony, I marvel at the diversity of the passing humanity. There are people short and tall, gay and straight and trans, fat and skinny, light and dark, and even a few wearing Gallaudet University T-shirts excitedly using sign language. The supposed promise of CRISPR is that we may someday be able to pick which of these traits we want in our children and in all of our descendants. We could choose for them to be tall and muscular and blond and blue-eyed and not deaf and not … well, pick your preferences.

As I survey the delightful pageant with all of its natural variety, I ponder how this promise of CRISPR might also be its peril, up there with the encoding of unequal opportunities. It took the laws of nature and of nature’s God more than 3.2 billion years to weave together three billion bases of DNA in a complex and occasionally imperfect way to permit all of the wondrous diversity within our species. Are we right to think we can now come along and, within a few decades, edit that genome to eliminate what we see as imperfections? Will we lose our diversity? Will we become less flavorful, like our tomatoes? Will that be good for our species?

Read it all.
