“Why would any sane person want to think about the human condition a millennium from now?” is a question I have heard every time the subject has come up. So, why bring it up?
Perhaps some reasonable speculation might help inform us today about how to lay foundation stones for the lives of our descendants. For example, simple math shows that, if each member of each generation between now and then produces two offspring, their descendants will aggregate in 3010 some 17 billion people! Surely we should care enough about those distant descendants to spend some time and effort imagining, and hopefully helping, the world they will inherit from us.
Today, though we think we know just about everything there is to know about our world, we still do not know what we do not know, for instance, about the mysteries of the oceans, the innards of earth and the environs of our solar system. Smart people everywhere are working on all those questions, to be sure, but mysteries abound. For example, we are increasingly uncertain about some of the key fundamentals of time and space; we now know there are lots of exoplanets around stars like our sun; we know there are limits to our current main sources of energy, but we do not yet know how to tap efficiently either solar energy or deep center of earth energy. We do know that for millions of years earth has had repetitive cycles of about 100,000 years’ length in which it slowly warms and then suddenly cools. We do not know quite where we are in the current cycle, but we believe man has raised our present point on the warming curve enough to create new challenges to the sustainability of the future of earth.
