These new DIY fabrication technologies are soon going to make laser cutting seem primitive. Soon, the physical part of modeling most anything is going to be almost trivial. So, here's the question: Will these capabilities open a whole new world of creativity, or will the ability for anyone to make anything perfectly make the whole enterprise seem pointless?
My prediction:
There will be a renaissance of old-school craftsmanship using hand techniques and traditional "found around the house" materials. That style of work is the one part of the hobby that the computerized techniques can't touch.
