I see 3-D printing as just one small area in the ever expanding world of technology. A lathe was needed to make the printer nozzle. Microcode and computers on a chip to control it. Hobbyist and robotics fan-boy websites, as well as thousands of youtube videos reveal amazing things people do in their garages and dens. 3-D printing is sort of an adjustable wrench in the larger scheme, as amazing as the milling machine or silicon lithography when they first came out.
