I believe positrons were supposed to be, what, holes in the Dirac sea? Or a time-reversed electron?There have been a number of road bumps on the way to the current models
Fortunately each one was a learning experience!
Again, @geordief dangerous to take the maths too literally.
Added Note: it’s worth noting that the Dirac and Feynman theories are formally equivalent and can still be used today depending on the situation. Feynman’s work led to his famous diagrams.
