This is one of the most exciting articles I have read in a long time. The article seems to claim, with some confidence, that we can expect antiaging drugs within ten years. Biotech companies will compete to develop new gene therapies. My life expectancy has at least four more decades without antiaging therapies! Thus, within a decade I can expect a positive feedback loop to begin. This, together with the new robots from Japan, begins to fulfill Kurzweil's prophecy.

Of course, if I want to enjoy any of these benefits, the species needs to survive these decades and the Singularity.
