Our lives were designed to be short, and our sense of foresight was designed accordingly.
We came from thickset forest and fields of tall grass. At any given time, our entire world was a short sight line about half the radius of a circle. Objects flitted in an(more)d out of our existence, and we flitted in and out of theirs. We moved forward through a thick sea senses, with the goal of surviving today and letting tomorrow take care of itself.
And most of the time, tomorrow would come.
It doesn't work anymore. I suspect our ancestors always knew it wouldn't last, too. But that fact was constantly weighed against the immediacies of the day, and found wanting.
It was different back then, though. The world was small. We survived by moving. If there was no hope where you are, press onward, and in a few feet, everything might change.
Today, the nature of our existence has changed fundamentally. But our minds haven't. We still think in immediacies. We still use whatever resources we see in our short half-circle line of sight, and press forward. We have leaned on the institutions of the past for too long, and it has caused us to keep borrowing from our future, at higher and higher cost.
The scale of the world we navigate today is massive. A time will come when there is nothing else 'onward' in which to push. And I fear that, in our short-sightedness, we won't recognize that end until we are well and truly over the edge. (less)
