In 1995, Danny Hillis came up with the idea of building a clock that would last 10,000 years.
I cannot imagine the future, but I care about it. I know I am a part of a story that starts long before I can remember and continues long beyond when anyone will remember me. I sense that I am alive at a time of important change, and I feel a responsibility to make sure that the change comes out well. I plant my acorns knowing that I will never live to harvest the oaks.
I want to build a clock that ticks once a year. The century hand advances once every 100 years, and the cuckoo comes out on the millennium. I want the cuckoo to come out every millennium for the next 10,000 years.
The Clock of the Long Now is a short video portrait of Hillis and his collaborators as they build this clock in a mountain in western Texas. I like what Hillis had to say about our future:
I'm very optimistic about the future. I'm not optimistic because I think our problems are small. I'm optimistic because I think our capacity to deal with problems is great.
