What I was mainly thinking about, though, was the saying "a little knowledge is a dangerous thing." We know so little so far. We act like we've unlocked the book of life, but we haven't. DNA is powerful, yes, and is a fascinating area of study; but we have such an oversimplified understanding of it. To me, DNA works as a whole, like a body: you can't say any one organ system is more important than another, they are all necessary. So to reduce all life to one molecule? Ridiculous!
Same with reducing disease to this gene or that; it's foolish and dangerous. As if just because you have this one segment of DNA, you're fated for a certain disease. It leaves out the "nurture" side of the "debate," though I'm sure it's great for pharmeceutical profits. Besides, if you go looking for problems, you'll find them. I'm sure we all have DNA riddled with errors, mutations, and potential for disease. But the system is self-correcting; many of those mutations never find expression. Thank you immune system-- patient, heal thyself!
You wonder why I fear our new technologies? They amplify our power far beyond our control, our restraint, our wisdom. We are the sorcerer's apprentice. But instead of a workshop, we're ruining the world.
