Be it resolved, let’s engineer a better human being.

We’ve come a long way since DNA was first discovered in the mid-19th century. Today’s scientists are using powerful engineering techniques to edit genes in human eggs and sperm, curing diseases and repairing defective genes before a child is even born. Some scientists are excited about these therapies, championing them as an exciting opportunity to create immunity to viruses, eliminate serious illnesses like AIDS, Alzheimer’s, and cancer, and possibly reverse aging. Like prior innovations in medicine and technology, why wouldn’t we embrace a science that allows people to live longer, healthier, and happier lives? Others are alarmed. They are worried that these new techniques raise a host of profound ethical issues. While eliminating genetic diseases is a worthwhile endeavor, many parents might be inclined to use this science to create designer babies: children who are smarter, taller, or have other supposedly desirable traits. And these tools aren’t cheap. They will surely be available to the rich first, creating a terrifying new dimension to the growing economic inequality crisis. Scientists also point out that ‘playing god’ and editing genes will alter our DNA code forever, and one mistake could inadvertently introduce new diseases into the human gene pool. While the desire to cure genetic diseases is a noble one, the manipulation of our DNA is more likely than not to push humanity towards a dangerous and dystopian future no one wants.
