Jeff Bezos spent $42 million building a clock inside a mountain

 Jeff Bezos spent $42 million building a clock inside a mountain that’s designed to tick for 10,000 years.

It’s called the Clock of the Long Now, and it’s meant to encourage long-term thinking. It ticks once a year, chimes once a century, and a cuckoo pops out every millennium. The whole thing runs on thermal energy and sunlight, and it’s hidden deep inside a mountain in West Texas on Bezos’ land.

It’s part art, part engineering, part philosophy. Some people say it’s a vanity project or a waste of money, others say it’s a powerful symbol of thinking beyond our lifetimes.
