Recently saw a headline that some company in the USA had 3D printed a car. Yesterday heard a news blurb that China has 3D printed a five-story building. This is going to revolutionize the construction industry, said the reporter. Gee no kidding.
The reporter also noted how fast all this is happening -- within the past two years. For years 3D printers were a novelty printing out novelties. For years hydrofracking had no measurable impact on the oil industry.
There's still a delayed reaction; societies haven't yet absorbed the vast changes upon them.
Economists, central banks, deer in the headlights.
