"We imagine that energy decline and economic collapse will eradicate all high tech, and reduce the whole planet to a preindustrial lifestyle, because it's easy to imagine. It's harder to imagine a collapse that's unevenly distributed. Historically, economic collapses do not reduce everyone to poverty, but increase the gap between rich and poor. I think the same thing is going to happen with technology: while overall resource consumption decreases, the proportion spent at the leading edge of technology will increase. Less energy will be spent moving physical stuff, and more will be spent moving information."
"Not only will there be a wider gap between the places with the highest and lowest technology, there will also be a wider gap between the highest and lowest technology used by an average person. Already there are African villagers with cell phones. In 20 years you may be living with a group of friends in an abandoned suburb, burning scrap wood for heat, growing open-source genetically modified sweet potatoes, and selling brain time to the dataswarm to gain credits for surgery to install a neuro-optical interface so you can swap out custom eyeballs."
