Never heard of it before. My first impression: I wish there were more science, but I liked this quote.

If you ask my eight-year-old about the Future, he pretty much thinks the world is going to end, and that’s it. Most likely global warming, he says—floods, storms, desertification—but the possibility of viral pandemic, meteor impact, or some kind of nuclear exchange is not alien to his view of the days to come. Maybe not tomorrow, or a year from now. The kid is more than capable of generating a full head of optimistic steam about next week, next vacation, his tenth birthday. It’s only the world a hundred years on that leaves his hopes a blank. My son seems to take the end of everything, of all human endeavor and creation, for granted. He sees himself as living on the last page, if not in the last paragraph, of a long, strange and bewildering book. If you had told me, when I was eight, that a little kid of the future would feel that way—and that what’s more, he would see a certain justice in our eventual extinction, would think the world was better off without human beings in it—that would have been even worse than hearing that in 2006 there are no hydroponic megafarms, no human colonies on Mars, no personal jetpacks for everyone. That would truly have broken my heart. When I told my son about the Clock of the Long Now, he listened very carefully, and we looked at the pictures on the Long Now Foundation’s website. “Will there really be people then, Dad?” he said. “Yes,” I told him without hesitation, “there will.”

I find it hard "believing" in a technological future too. I have that "last paragraph of a long book" feeling. But they're right, it's probably not healthy.
