"The prospect of genetically eliminating crippling diseases is certainly appealing, but this promise masks a darker reality."

"First, there is a difference between genetic engineering and the extremely promising field of gene therapy, in which doctors use CRISPR technology to repair the DNA of defective nonreproductive cells -- allowing them to treat cancer, genetic disorders and other diseases. In gene therapy, the genetic changes affect only the patient. In genetic engineering, scientists alter the entire genetic structure of the resulting human being -- changes that are then passed on to future generations. Playing with humanity's genetic code could open a Pandora's box. Scientists will eventually be able to alter DNA not just to protect against disease but also to create genetically enhanced human beings. The same techniques that can eliminate muscular dystrophy might also be used to enhance muscles to improve strength or speed. Techniques used to eliminate dementia may also be harnessed to enhance memory and cognition. This would have profound societal implications...."
