I was referred to you by Andrew D. Nystrom.
While I am a firm believer in the fact that humans seem to have difficulty seeing past 5PM, I am occasionally impressed by the few. I find your clock idea a step towards 5:30PM. An extra '0' so humanity can continue for another 98,000 years is reassuring. This short sightedness is echoed throughout the vaults of time by many cultures like the Mayans and Microsoft (hmmmm, I wonder if it is the letter 'M' that is the issue here).
I believe that Mr. Nystrom thought that my project conformed to your thinking ... past the here and now. I am building a space habitat so that humanity can be diverse and our legacy can continue beyond the limits of Earth and beyond the next 100,000 years. Future thinking is not a function of time but rather an exercise in the growth and deployment of knowledge. Our project is slated to take about 25years to complete, but that goal is not the premiss of the task. Our objective is a growth of understanding that we are stagnant and unwilling to utilize our potential ... oh yeah, and we are building a habitat to house 2million people in outer space. We walked on the moon in the 60's and our fundamental knowledge by the late 70's was sufficient then to put mankind in permanent residence in outer space. Instead we procrastinate and divert economic efforts to tiny foot steps out of our cave. Too much of our thinking is that of the philosophy of the pharmaceutical industry "treat the symptom, there is no future in solving the problem".
Not 'Long Now', humanity will have exceeded its fragile eco-bubble and will guarantee its longevity by expanding to self created habitats and shortly thereafter occupy other worlds.
Food for knowledge!
