I have heard that when transistors were new, there were a bunch of people claiming the theory behind them was nonsense because it treated current in p-doped semiconductors as a flow of positive charges (holes.) (These were not physicists - mostly hobbyists, some electricians and maybe a few EEs.) Once you get to capacitors, inductors, transmission lines and antennas, you are no longer just considering electrons, but also fields (usually via classical approximations to the underlying QED.) In electrolytes, you have both positive and negative ions...
