It does not "lead" anywhere. It's a wandering in the wild. Some paths lead to cliffs, some will keep you going for a long time. A vast number of paths will be taken, but in any given time you only see the species - better yet, the individuals - who have not fallen off a cliff. I like the idea of evolution, because "it is what it is". It happens whether you believe it or not. It has no goal, it just happens. And, it's not that evolution "changes" species, it's that whoever survives becomes the definition of what a species is at all, therefore "evolution" is just the observable outcome, the process is natural selection. So, it's pointless to "blame" evolution, to say "it is not good enough". I, you, we don't even know what's "Good enough" and for whom. Even whatever we consider "humanity" is the outcome of our natural selection. Your very wish to live forever, is the outcome of our natural selection. The wish to genetically engineer our species' future members, will only be judged good or bad by its outcome, not by our planning. What you see now is what works, and the proof it works is we are still here. For example, if we end up destroying the world and our species with nuclear weapons, the path of evolution giving us intellect will have proven to be a bad one for this branch of DNA called "human species". I can only say I have a very bad gut feeling about conscious genetic altering of humans, and I trust there are many arguments to find if I analyze it. Perhaps it's only some aspect of my DNA's self preservation not wanting to lose over some made-up DNA.
