But in our real world, gene editing tools like CRISPR make futures of designer babies and genetic discrimination feel painfully conceivable (actually, it’s already happened). Even more frightening, many proteins encoded in the human genome remain largely unknown, and, as a result, we don’t really understand what their genes do.
