bootstrap problem ahead! (Score 1)

This first robotic arm makes a second robotic arm on a facing surface by picking up miniature parts carefully laid out in advance in exactly the right locations so the tiny robotic arm can find them. I see. And who made those exponential many miniature parts and laid them out carefully in advance? An army of even tinier, exponentially self-replicating Waldos, perhaps? Looks like the good old chicken-and-egg to me..
