It is easy to see how you could be tempted. It might start with genetically screening your children for a lower risk of a hereditary cancer. Or perhaps with a pill that promised to keep your memory fresh and clear into old age.
But what if, while you were having your future children engineered to be cancer-free, you were offered the chance to make them musically gifted? Or, if instead of taking a memory-enhancing pill, you were offered a neural implant that would instantly make you fluent in all the world’s languages? Or cleverer by half? Wouldn’t it be difficult to say no? And what if you were offered a whole new body - one that would never decay or grow old?
