Slab,

My question to you isn't complex at all. The perpetual industrial growth model is not sustainable. Pretty simple. I guess that makes it a trick question. And indeed, your question is "equally complex" in that it too, is simple. The answer is none. Because the model is fatally flawed, the answer is not predictable because there are several possible outcomes, including global socio-economic collapse, pandemic, or attenuating dynamic socio-economic equalibrium that rotates the locations of production and consumption, and other alternatives. That does get a bit complex.
