Evolution happens. Nothing can stop it. Modern technology simply changes the selection forces that act upon our genetic variations.
True, human beings have become physically weaker compared to our ancesters (primitive humans are much stronger than us, and so are the modern great apes). I just recently read that a chimpanzee (our closest modern relative) typically has five times the upper body strength than an adult human. But our intellect has evolved to a level that far surpasses even the most intelligent animal.
We just have different forces (I guess you can call it "artificial" selection instead of natural selection) that mold the way we evolve. Instead of having infectious diseases that kill us, we have heart disease, obesity, and cancer. Evolution happens constantly simply we still die and some of us die before we reproduce.
It'll be difficult to foresee what the product of this different sort of natural selection will be, but I guess none of us really have to worry about that. We won't be around to see the result.
