Don’t be afraid Father of Giants. Techs will adapt. A High current transision course and a handshake is all that’s needed. Electric cars have been around since the dawn of the automobile. Battery technology has made great advances. That’s a good thing. You still get to keep your relic of a diesel. It’s been outdated for a long time and some of us like the old stuff because it’s easily understood comparatively speaking. Such is life in many ways. You can stay in your bubble of “good old days” or you can advance to modernity by trial of error like most folks do. Either way, you and the techs will be fine.
