Efficiency and robustness are mortal enemies, inherently opposed on the value of redundancy, which robustness requires but efficiency eliminates. This talk argues that, by emphasizing efficiency alone, computer science is often optimizing the wrong thing, and we could do better, and should, by recognizing and managing the tradeoff explicitly. An illustration of efficiency's costs is presented, along with discussion of possible computing mechanisms when robustness is emphasized even over correctness.
