The proof of Fermats last theorem did not involve many areas of mathematics. It was primarily proved via algebraic geometry. That’s also not true about wiles productivity... he first discovered the proof in 93 but then when he talked to people about it an error was found. He eventually fixed the error in 94 and then in 95 it was published. No mathematician waits to publish the proof of one of the greatest unsolved problems in mathematics.
