USB 3.0 was renamed to 3.1, but that was confusing, conflicting with USB 3.1, so it was rerenamed to USB 3.2 Gen1, so that people understood that 3.0 was ACTUALLY the first generation of USB 3.2
But that caused problems with USB 3.1, which was faster than USB 3.2 Gen1, so it was renamed USB 3.2 Gen2, so that it crystal clear was faster than USB 3.0/3.1/3.2 Gen1.
But that caused problems with USB 3.2, because 3.2 is just two lanes of USB 3.2 Gen2, so 3.2 was renamed to USB 3.2 Gen2x2 so people knew it was TWICE as good as USB 3.2 Gen2.
The problem now is that USB4 eliminates all that clarity, so right now the big marketing push is to clarify it as USB 3.2^2 Gen1: The Reckoning.
To resolve the conflicts of historical naming with USB 1 and 2, those will be renamed USB 3.2 Gen √0 and USB 3.2 Gen √-1/pi.
