Hmmm, I don't remember mentioning 'immoral' in my post. As for the decision on ethics and literally everything, I have literally been waiting for people all year to 'be ready' to work on this. But I am now tired of waiting and decided to just out with it. I believe things will work out well eventually.
The point is not so much about immortality or all-powerful beings as it is about giving humanity another kind of existence we have not had before, but which appear very plausible to me. So we take all the best things we have discovered/learned from our lives and try to redesign human life the best way we know.
If anything is worth doing, this is worth doing also.
