Perhaps he has a point. We may have spent too much time and effort dealing with electrons and electronics. However, switching to protons and protonics is not the solution. We really deal mostly with "hole flow", which is where current is defined as the absence of electrons flowing in the opposite direction of the electrons.
Holetronics does sound a bit odd, but after a few months of mindless repetition, might prove to be survivable.
I suggest that the first step be to change the convention of having signal flow from left to right on schematics, to flowing in the opposite direction to indicate that it's really hole flow. As a side benefit, it will make schematics easier to draw by left handed engineers. Maybe also put the title block in the lower left corner, move the zero position on panel meters to the right, and require that digital displays be switchable to little-endian when displaying hole flow.
