Why a 10,000-year clock is being built under a mountain – and why 10,000 years is too long
Construction is underway on a “10,000 year clock”. This is a clock that will have a year hand, a century hand, and a cuckoo that comes out every 1,000 years. The American inventor Danny Hillis wrote about the idea in 1995, and, thanks to a US$42m investment from Amazon CEO Jeff Bezos, the clock is now being installed inside a Texas mountain. The aim of building a clock designed to work for 10 millennia, Bezos says, is to encourage long-term thinking.
