People keep saying 3d printers will revolutionize the world. They are right, just not in the HOW. The children growing up with desktop manufacturing available to them are the ones that will revolutionize the world. The ability to create without the prerequisite traditionally required craftsmanship is what will do it.
Look at the underlying shift in base assumption of my 3 year old, it's not *if* I can fix her toy – that's a given in her mind, it's that it's as simple as pressing a 'print' button on a computer.
That's what blows my mind.
