XKCD 2501 parody. Left person: "Division optimizations are second nature to us compiler engineers, so it's easy to forget that the average person probably only knows the Knuth algorithm and Montgomery reductions." Right person: "And Barrett reductions, of course." Left person: "Of course." Bottom text: "Even when they're trying to compensate for it, experts in anything wildly overestimate the average person's familiarity with their field."
