Now, if we can get the Religious Right out of politics and give scientists a free hand it won't be long before genetic diseases are eliminated, designer babies are the norm, force-grown replacement parts for any piece of your body are available with a simple cheek scraping, and mail order copies of your favorite porn starlette are available for only $29.95 plus shipping.
