Bestselling author Walter Isaacson has established himself as the biographer of creativity, innovation, and genius. He wrote about Einstein, a genius of the revolution in physics, and Steve Jobs, a genius of the revolution in digital technology. Though the past half-century has been a digital age, based on the microchip, computer, and internet, Isaacson argues we are now on the cusp of a third revolution in science—a revolution in biochemistry that is capable of curing diseases, fending off viruses, and improving the human species. With the invention of CRISPR, we can edit our DNA. CRISPR has been used in China to create “designer babies” that are immune from the AIDS virus and in the U.S. to cure patients of sickle cell anemia. With the life-science revolution, children who study digital coding will be joined by those who study the code of life—and all the moral dilemmas this brings.
