More specifically, advances in today's medicine and technology make it so that modern humans do not have to rely on natural selection to survive.
People who are prone to disease will not die because of advances in medicine; instead of thinning the herd and having only the strong survive, humans with an evolutionary weaknesses to disease are allowed to pass on thier genes
Similairly, those not fit to survive physically are now protected by technology. the weak and disabled are surviving and able to pass on their DNA as well, allowing flaws to come though and survive time.
Sure we are getting smarter and are able to tackle new problems, but are we weakening the human race to a point of no return if our link to technology was somehow severed?
