Re: Envisioning the world of 2100

An exponential curve assumes endless advancement of technology and infinite resources. That alone makes it highly suspect. Technology can only advance to the extent that resources allow, and we are approaching a crunch in numerous resources over the next several generations: oil, fresh water, phosphates, rare earth metals, the list goes on. A logistic curve therefore makes plenty of sense. It is foolish to think our technological growth will never top out.
