“Someday soon”

Based on what exactly makes you think this?

Humans have been around for thousands of years. Look at what we've accomplished in the last hundred. We have artificial heart pumps now. In the next two hundred years, if cancer research doesn't slow down too much and if we find some quick fixes for neurodegeneration, I think it's entirely plausible that 90 will become the new 60. I doubt I'll be around for it, and we might never hit the "life extension outpaces people reaching their life expectancy" medical immortality Holy Grail; but in the abstract, there is hope.

Judging by https://news.ycombinator.com/item?id=46923612 and https://news.ycombinator.com/item?id=46901862, I expect unsupp0rted's logic is closer to "we'll build superintelligent AI servants some time next week, and that will usher in a new golden age"; but that doesn't make the claim invalid.
