This enables us to keep many sick and diseased and extremely disabled poeple alive - people who would never have survived 50 or 100 years ago. This really alters the human genome through the elimination or emasculation of "natural selection." Intead of dying, these people with genetic defects and disease are living - and passing the defective or inferior genes on to children, and thus weakening the human race. This is why there is so much more disease and disability today. The next step, to correct the unintended consequence of advanced medicial treatments, is to genetically engineer people - before or after birth - to eliminate as many defects as possible.
First, progress in this area will come in the form of implanted genes that correct the way our DNA builds and repairs our bodies. We will become genetically resistant to disease, viruses, and be able to minimize the probability of birth defects. These will permanently alter our DNA, enabling us to pass the superior genes to our chilren, rather than defective ones. One day maybe we will also be able to do the same for genes that govern intelligence, athleticism, size, etc. Of course it sounds rosy and noble, but there are those unintended consequences to deal with as well . . . but I truly believe it will happen. As far as "playing God" goes, I believe it is our duty to him and ourselves to make the most of what he has given us - this also means using our brains to improve the quality of life for everyone. We began by using herbs for treament, then we developed surgery, and chemicals and hormones, and now we are looking at the next frontier - gene therapy. There will always be moral dilemmas in medicine, but the general idea of gene therapy is a good one. Definining the parameters will be the most difficult thing for us as a world community.
