“CRISPR” (pronounced “crisper”) stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR–Cas9 genome editing technology. It may soon be possible to eliminate certain diseases genetically, to change the eye color (and more) of babies, and to lengthen the lifespan of humans. Many strides have already been made, such as the means to fight cancer using gene therapy. To some, this is all “playing God,” while to others it is progress: the “search for better explanations, leading to discoveries,” as David Deutsch put it in “The Beginning of Infinity.” Whatever one’s beliefs, there are problems with all technologies, as discussed in the new book on social media interfaces: “Dawn of the New Everything” by Jaron Lanier. In my novel “The Methuselah Gene” a neutered HIV is used, not as a cancer therapy as in the Breakthroughs show produced by Ron Howard, but to implant a longevity gene taken from a bristlecone pine tree past the blood/brain barrier, and extend human life by decades. A pill to do something like this is now in the works, and may be here within a decade. How much would such a pill cost, and will only the super rich be able to afford it? In the New Rules governing culture, before our young icons can acquire near immortality via science, what if nefarious forces tested it on a small town in Iowa without their knowledge or consent…and discovered that there were side effects?
