That is the real lesson of Fermat's Last Theorem. The margin was too narrow. It took 358 years and the entire evolution of modern mathematics to contain it.

The proof of Fermat's Last Theorem was finally built in 1995 by Andrew Wiles (with help from Richard Taylor). But Wiles didn't actually look at $x^n + y^n = z^n$. That is the real lesson of Fermat's Last Theorem
