But also imagine that the algorithms you write had to work (perhaps slightly differently, but essentially the same) when hit with bit-flips in the code. How would one do that? Perhaps have multiple copies, or coding redundancy, or fix-up routines, or fall-back instructions. All the kind of stuff that mother nature already figured out. But that should be unsurprising, since without that robustness, the evolution thing would kill our progeny almost every time. Building the robustness is almost as important as building the functionality.
