Future Existence.

Who does man think that we are to overcome the definition of existence?
I just watched a documentary on the evolution of man and mechanics, rather the merging of man and mechanics. Transcendent Man is about the the thoughts, ideas, and predictions of the inventor Ray Kurzweil. This man has devoted his life to improving the existence of man kind, inventing reading machines for the blind, prosthetics that are plugged into your neurological system for the lame, the list goes on and on.
The claim that struck me the most was the idea that because of the technology that we have created thus far we, as humans, will be able to advance technology enough to overcome health issues. We will be able to run longer, hold our breath longer, live longer. We will be able to advance our human bodies to the degree of being able to plug ourselves into the intranet to obtain an infonaut amount of information. He even went as far as to claim that we will be able to bring the exact likeness of our dead ones from the grave or anyone and replicate them enough to be as actual human beings. And the most scary thing of all of those claims is that we have the technology to do it.
Have we put our trust in an intelligence that we have created? Have we gone as far as claiming we could be like a god?
Now more than ever I am convinced we are very much living in the last days. God will not be tampered with. And we are diving head first into an idea that will ultimately destroy us, and not in the least bit will it improve our existence.
