Life span, medical enhancements and immortality

A friend posted: ... And if past enhancements (in medical) are any indication then we will get to know exactly what cause death and how to reverse or stop this from happening. In my honest opinion, it's not question of IF but WHEN.
Just take a look at Ray Kurzweil's Transcend: Nine Steps to Living Well Forever.
... Moreover I've found following on wikipedia about Ray Kurweil's stance on religion (http://en.wikipedia.org/wiki/Raymond_Kurzweil)
... According to Kurzweil “The primary role of traditional religion is deathist rationalization—that is, rationalizing the tragedy of death as a good thing. In order to benefit from what the Singularity can bring, we need to overcome our deathist rationalization. We need to sweep traditional religion out of our road.”
Answer: Raymond Kurzweil: Interesting and well accomplished... wow! As far as life span is concerned, well of course it can be possible to increase the average life span from the current less than 100 to may be 200, 500, 1000, who knows. But will it make humans immortal, or help escape reckoning?
Some relevant verses are:
The Holy Quran2:96 And verily, you will find them (the Jews) the greediest of mankind for life and (even greedier) than those who ascribe partners to Allah (and do not believe in Resurrection - Majus, pagans, and idolaters). Everyone of them wishes that he could be given a life of a thousand years. But the grant of such life will not save him even a little from (due) punishment. And Allah is All-Seer of what they do.
2:28 How can you disbelieve in Allah? seeing that you were dead and He gave you life. Then He will give you death, then again will bring you to life (on the Day of Resurrection) and then unto Him you will return
3:185 Everyone shall taste death. And only on the Day of Resurrection shall you be paid your wages in full. And whoever is removed away from the Fire and admitted to Paradise, he indeed is successful. The life of this world is only the enjoyment of deception.
