I really like the 3d printer analogy. You can still make some pretty cool stuff, you can make some pretty complex things if you carefully design the whole system and put in the effort to print each part individually, and quality depends both on how good of a 3d printer you have and on the proper use of it. "3d print me a new house" is still a pipe-dream: you'll get some miniature facsimile of a house, sure, but a proper house requires proper tools and expertise.
