I think other fields it's gotten much harder to explain the results. For example, it was a big deal in number theory a few years ago when 10 authors proved a weak form of the Shimura-Taniyama conjecture for number fields with complex multiplication. (The simplest case of Shimura-Taniyama implies Fermat's last theorem.) It would take an entire course to explain just the statement of the theorem.
