Apparently these people never studied history. This clock will either be forgotton or stripped or both in the next 200 years. Only stone structures of no value survive the fall of civilization, and every civilization falls.
If our civilization beats all odds and continues to progress, the clock will seem childish within 50 years.

Hmmmm
I like the idea... I think it\'s both really cool - and it\'s the type and quality that I like to build.
Enduring is a good word.
I am interested in the power supply for it... very good.
As far as the empire USA crumbling into a festering wasteland of GM toxic weeds and mutagenic dust...
Yes and when the phareo snuffed it and time rolled on for a bit, the people said... \"See all that nice shiny lime stone on the pyramid - we can use that we can.\"
The pyramids only survived being totally repurposed because of their size.
This will be an interesting project to watch - from my low earth orbit space kingdom - for all eternity with Jeezers.

How long is the warranty?

Hmmmm, reminds me of the Myans.
Around 12000AD they\'re going to have movies about the end of the world in 12011, because that\'s when the clock stops.

The aim is not necessarily for the clock to last a long time, but for people visiting it to get some kind of an impression of the scale of time and human history. The premise being that short termism is the cause of a lot of the worlds problems.

I am amazed at how mechanical this is....more difference engine than 21st century. Very Jules Verne.

Get used to thinking in terms of infinity. There was NO first cause. The universe has always existed, it is infinite, and it will exist forever. Our observable space in this vastness is a mote in time.

Can it speak cockroach? Then at least some'body' will be able to understand the 10,000 yr ring.

This reminds me of what St.Francis is suppose to have said when asked what he would do if he knew the world were to end tomorrow.
He smiled and replied, "Plant a tree?"
This is more about the message than the machinery.
"Imagination is more important than knowledge- for knowledge is limited to all we now know and understand, while imagination embraces the entire world... and all there ever will be to know and understand." -Albert Einstein

This is brilliant - but how are they going to keep dust, dead birds, bats, bob cats and rodents out of it?
Or even weeds?
It\'s like the erosion on the nuke fuel cannisters in the cooling ponds - caused by bacteria eating the stainless steel.
How can this be future proofed against things getting into it...
