The biotech boosters, of course, don't see things this way. Many of them insist that any conceivable application of human genetic engineering is essential to medical progress, and that the possibilities, no matter how speculative, trump all other considerations. Thus they shrug off the likely outcome of embryo cloning—that it will...
