Most living organisms quite logically think of the immediate future.For eg. I plan what happens in the next six months and I guess that maybe with many of us. Some people plan for a year or two. Fewer people for 5 years.
What abt planning for the humankind for the next 100 years? The next thousand years ? You don't, right ? Nobody does.
Civilization is revving itself into a pathologically short attention span. The trend might be coming from the acceleration of technology, the short-horizon perspective of market-driven economics, the next-election perspective of democracies, or the distractions of personal multi-tasking. All are on the increase.
There is an interesting project called Project Longnow which takes projects which goes on for thousands of years. It kinda sounds cool and very "culture and humanity driven".
Take two of their products :-
One is a mechanical clock, powered by seasonal temperature changes. It ticks once a year, bongs once a century, and the cuckoo comes out every millennium
The other is called Rosetta Archive serving nearly 100,000 pages of material documenting over 2,500 languages because of accelerated loss of the world’s languages. Just as globalization threatens human cultural diversity, the languages of small, unique, localized human societies are at serious risk
Have a look at the Longnow website and the Photos of the Clock which looks majestic. Also the way the specifications for the clock is written requires thinking which needs to take thousands of years into account !
