Turns out that the Club of Rome weren't completely wrong - everything that's happened since fits in their model. The Club of Rome (and Malthus before) said that if your economy grows continuously then eventually you'll run out of stuff. Economists since have poopooed the idea by observing that food production has in fact increased. This always struck me as a little naive, as food production increased by converting more and more biologically powered processes to oil powered processes. So if we assume that oil is an infinite resource, with infinite extraction availability, then yes, there is no problem. But of course it isn't. (Oh, but solar! fission! fusion!) If we keep growing we will eventually grow faster than light can expand from earth.
The ultimate strange loop, the universe is my brain, I live in my brain. (Of course, you do too!)
