It's pretty remarkable that despite Feynman Diagrams being invented in the 1950s, before computers and computer science, they are still state of the art so many years later. It was back at the time where physicists did most calculations by hand.
You'd have thought something more efficient would've turned out by now, since there was barely a sensible definition of efficiency back then.
