For consumers, wasn't USB 3.0 just USB 2.0 but a few times faster? USB-C is what is confusing to some people. Replacing micro USB was straightforward enough, but replacing USB-A is a rough process.
USB 3 is also what kills your wifi if things aren't properly done (e.g. https://medium.com/ghostbar/your-usb-3-0-hub-is-killing-your... - and it's not only a mac problem), so it's not just 2.0 but faster.

I guess?
Except that my desk has three USB cords, each with a color-coded label so that I can tell what each one is for. One is seemingly the only one that will charge my e-reader, but only does low speed data transmission so it never really gets used for anything but my e-reader. Another is power only and therefore useful for charging devices without my computer attempting to talk to them. And a third is a proper, modern (ish, I suppose), well-behaved USB 2.0 cable.
You could geek out and learn the difference of upstream (A, host) and downstream (B, device) ports, the various types of B port sizes, and that was it. Later USB 2.0 was introduced and just (bam!) made it all 40 times faster, but it still logically worked pretty much the same.
Then USB 3.x came and just blew all that to h-ll, which is frustrating for both old bearded geeks, and* new/non-technical users.
