For example, we might create people with gills to help alleviate our population problem. But even if we cannot define what it means to be a better human, our culture has ideas about it. They may be more efficient, faster, stronger, and more intelligent, but we cannot control how they think. They will think that they are superior, and they will have the numbers to prove it. What we don't know doesn't bother us as long as we are able to manipulate our environment.
Man seems to most want the powers to kill, to expand, and to create.
Our artificial world would be based on economy. To create new life all we need to do is create a new species. The difference is that we were still operating under the constraints of natural limitations. We are altering ourselves and our environment and world. Natural connexions with one another and human contact are minimized in our world through our technologies.
