3D Printing Future Timeline

[3LawsSafe]

"If, by some miracle, a prophet could describe the future exactly as it would happen, his predictions would sound so absurd, so far-fetched, that everyone would laugh him to scorn." -Arthur C. Clarke.

"Any sufficiently advanced technology is indistinguishable from magic." -Arthur C. Clarke

Both of these quotes describe 3D printing almost exactly, specifically the second. I look forward to a printer printing a printer. If I have enough solar panels (which are printable), and enough material, 1 printer can become 2, 2 can become 4, 4 can become 8, and in 30 doublings, you'd have over 1 billion printers, enough for nearly every home in the world. The standard of living worldwide will skyrocket, the costs of living will plummet, and a golden age may well begin.
