Error correction techniques originally explored by J.Von Neumann, and further worked on by many, e.g. A.Toom & Peter Gacs (cellular automata), Bruce Maggs (VLSI) make it possible for a computer to function exponentially long despite a small-enough random constant fraction of bit errors either due to mis-manufacturing or noise. In practice so far, these techniques have been practically unused; instead they've just made everything very reliable. (By the way, there already was the word "robust" hence no need to invent a new word "antifragile"?)
