@estelle i think he is making a gross logical error or at least uses terms in very narrow ways. "Technological progress" is not a one-way street.
Technology is the sum total of cultural adaptations that make use of the external environment. It has countless dimensions. We choose which ones we explore and develop and towards what aim.
The idea that we can have large numbers of people on the planet living comfortable lives without sophisticated technology is not just wrong, its dangerous.
