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.

Sometime in the next 5 minutes, in evolutionary timescale terms.

We built the first calculating machines yesterday, and a few hours later they took us to the moon. Now we’ve got vastly more powerful ones in our pockets and they have the sum total of all human knowledge and infinite patience for our questions.

Give it a few more minutes. We’ll know soon enough if the sand we’re imbuing with life is our salvation or our doom or something else entirely.
