This is something that explores current things (3d printers, CNC plywood cutters, etc) that could gradually play larger and larger roles in the fabrication of identical -- or better yet, identical with improvements -- copies of themselves. https://www.youtube.com/watch?v=l4tYIX_QJ2Q https://www.youtube.com/watch?v=l4tYIX_QJ2Q This will most certainly happen gradually, and will probably involve a whole cluster of machines.
