10,000-Year Clock Ticks to Life in Texas Mountain

A monumental 10,000-year clock, designed to track time for millennia, has recently achieved a significant milestone. Sunlight successfully synchronized the "Clock of the Long Now" within a Texas mountain, a project initiated over thirty years ago by computer scientist Danny Hillis.

This ambitious endeavor, primarily funded by Amazon founder Jeff Bezos, utilizes robust materials like titanium and ceramics to ensure its longevity. The clock is engineered to tick annually, chime for each century, and present a cuckoo display every millennium, serving as a philosophical counterpoint to modern short-term thinking.

Located remotely to protect it from theft and environmental factors, the clock's construction is nearing completion. Hillis's vision for the clock is to encourage a broader perspective on time and decision-making, addressing the growing bias towards immediate gratification prevalent in today's digital age.
