I see rough issues coming for A+ students in terms of identifying the sudden proliferation of USB versions and ports, Thunderbolt versions, “alternate modes” and “multiplex modes.” Consumers are going to face lots of compatibility problems, because there are so many modes: some cables do one thing, while other cables that look identical do different things. And how about Thunderbolt over USB? Nightmare is a legitimate description.
