Man, you are all so afraid.
Simple is a matter of perspective. Bacteria is simple. We are not. We are complex. We are complex because we are capable of interacting with and manipulating our environment. This is just more of the same.
Maybe it's not for everyone but for those who can adapt to this change, it opens an incredible host of new possibilities. It is simple historical fact that those who resist change the most are left in the dust and then overtaken by everyone else. Just look at the Middle East, Africa, 'native' races on each continent.
Sure, there will be issues that come up, but there will be different approaches and solutions as well. Humanity has stopped evolving physically. Hereditary diseases are coped with and physical and mental issues persist instead of being weeded out as they once were. This is both strength and weakness of living together as a society.
I'm for the idea of directing and controlling changes. Just because we change doesn't mean we reckless and heedlessly toss away moral values at the same time. Even as I changed from catholic to atheist, there were still many moral foundations that I kept with me. Because they still work but have a different, rational explanation to back them.
That logical foundation doesn't just vanish. Especially when logic is the force behind these technological advances.
If you cannot mentally adapt to physical changes, you will be weeded out and humanity will evolve mentally without you. Make no mistake, there will be losses and gains with modification. You will have to figure out the best route for you.
