He notes at the end to ignore maker culture but why not consider that as possible to reach the masses? With things like the Arduino and 3D printers making hacking easier and easier, maybe non-nerds will start (return to) building things.
One thing to consider is that the usability and maturing of the mainstream tech has helped it's easy adoption by people who otherwise wouldn't be bothered. I'd say the same thing will happen with 3d printers. Possibly we will see an easy abstraction over the top of things like the arduino - roomba type gadgets which are customizable?
