GENETIC PROGRAMMING. “The researchers thought this would provide insight on more efficient circuit design, but the circuit that evolved was so bizarre they couldn’t even understand how it was doing the task. Recreating the circuit on another identical system makes it fail, so apparently it relies on quirks and imperfections in the transistors to function. No human would ever design a circuit this way.”
