I’m not counting on runaway technology. The master resource that allows the complexity (and comfort) of our society is energy; technology is just the way we use energy to transform/ make something. No technology produces energy out of nothing. We still depend almost completely for our energy on fossil fuels http://www.ogj.com/articles/2017/01/bp-energy-outlook-global-energy-demand-to-grow-30-to-2035.html; over 80%. Of these fossil fuels it is oil that is the most flexible and useful. Our technology is solidly locked into oil. The Energy Return On Investment (EROI) https://en.wikipedia.org/wiki/Energy_returned_on_energy_invested has gradually been reducing and for some sources is close to 1. That is because the easy oil is running out fast. I assume you say that technology will open up new sources of energy? Have a look at http://naturalpatriot.org/2007/04/13/the-next-energy-transition/ to see how long it takes to transition from one source to another; it takes 30-40 years for a meaningful transition. The scale and importance this transition should have gotten so that there would have been an fighting chance of succeeding has been, and is, way to small (not even looking at climate change here). This is one of the key issues of our time, yet you don’t read much on this in the media… We’re too late, and while I don’t have the reference ready, this is also confirmed by government stakeholders.
And oil is not the only thing we’re running out of: http://www.visualcapitalist.com/forecast-when-well-run-out-of-each-metal/
There is so much that is not covered in the media, yet that should be. Much of what we see on the news are the symptoms of the underlying issues.
