Why do people fear the application of human reasoning to the creation of life forms? Do you likewise fear human engineering when it comes to such things as, bridges, buildings, and airplanes? Perhaps all you people terrified of genetic engineering should move into caves, and wear fig leaves for your underwear.
You folks seem to have no concern with the fact that random mutation and normal biological processes have the potential to create harmful organisms. In fact, as far as I know, ALL the harmful biological entities that have affected the earth to date have all come about naturally without any human intervention needed at all. Can you provide even ONE example of some human engineered plague or supervirus, or rapacious engineered lifeform?
The potential of applying our human intellect in guiding evolution and developing organisms that benefit us and the environment is staggering. But the fearmongers want to shut it all down prematurely, apparently preferring to let random chance be in the driver's seat. Yeah, sometimes humanity builds a titanic, or other engineering disaster, but is that sufficient reason to turn the clock back and reject intellect in favor of base animal nature? You can't get back into eden folks. It's much too late to spit out the apple
