"In a recent xkcd's alt text, Randall Munroe suggested stacksort, a sort that searches StackOverflow for sorting functions and runs them until it returns the correct answer. So, I made it. If you like running arbitrary code in your browser, try it out."
That idea might approach something useful if it was combined with memory for how various algorithms have done and the ability to optimize over time by choosing better algorithms. It would be sort of like a meta-algorithm.
