Moore’s Law Estimated This Puzzle Would Take 35 Years to Solve

In April 1999, cryptographers at the Massachusetts Institute of Technology (MIT) conceived a puzzle that was expected to take 35 years to solve. Last month, however, self-taught programmer Bernard Fabrot revealed that he had cracked it. The Belgian spent three and a half years working on the conundrum. As MIT’s Computer Science & Artificial Intelligence Lab explained:

The puzzle essentially involves doing roughly 80 trillion successive squarings of a starting number, and was specifically designed to foil…
