Refusing to turn reality on its head for a null change in the end is something else entirely.

I do agree with you, just want to give voice to the other side of this. Don’t underestimate just how much of a barrier this confusion is in teaching. It’s confusing. Students who are new to electricity almost universally hate this, and in some cases it can cause misunderstanding, miscommunications, etc. There is a genuine cost to this mislabeling, and there would have been effectively no cost if electrons’ charge was considered positive instead of negative.

As I said, I do agree that in practice, with all the existing knowledge, writings and technologies that all agree that electrons are negative, it would be a global disaster if the labeling was switched. There’s no question about it. But I kind of disagree about “null change”, it’s true that it wouldn’t change what we can create or (almost) any of our equations, but it absolutely would make it easier to teach it to future generations.
