A fascinating and inspiring meditation on aerodynamics.
The climate crisis as technical debt:
What we’re dealing with is hundreds of years of something that software world calls technical debt. Technical debt is the shortcuts and trade-offs engineers use to get something done either cheaper or in less time, which inevitably creates the need to fix systems later, often at great cost or difficulty.
Some technical debt is understood up front, some comes from builders being ignorant of the system they are working in. Most of our planet’s infrastructure is mired in huge amounts of technical debt, most of which we didn’t know we were signing up for at the time, some of which we’re just incurring recklessly as we go along, unable to face the scale of the problem and pushing it off on the next generation.
So, could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own? Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far.
Is the emergence of a technologically advanced civilisation necessarily contingent on the easy availability of ancient energy? Is it possible to build an industrialised civilisation without fossil fuels?
This thought experiment leads to some fascinating conclusions.
So, would a society starting over on a planet stripped of its fossil fuel deposits have the chance to progress through its own Industrial Revolution? Or to phrase it another way, what might have happened if, for whatever reason, the Earth had never acquired its extensive underground deposits of coal and oil in the first place? Would our progress necessarily have halted in the 18th century, in a pre-industrial state?
