"If nothing else, the simple fact that human intelligence follows a bell-curve should tell us that there's always going to be a large class of people who cannot function at the highest level of production. Those people need factory jobs, or farming jobs, or other lower-skill industries that pay a decent salary." Well said. The jobs we're creating are achievable to a progressively smaller segment of the population, and that's a huge problem. I wonder if as we run out of easily-mineable resources, we'll start creating low-skilled jobs again, in the recycling of the already-mined resources - garbage mining, effectively. If China's hold on rare earth metals, for example, continues to increase, I can imagine this being an important job area.
