Ars Technica just wrote an article about the confusing names of USB versions https://arstechnica.com/gadgets/2019/02/usb-3-2-is-going-to-... and now they have another one about this name. https://arstechnica.com/gadgets/2019/03/thunderbolt-3-become...

As someone who knows next to nothing about how USB actually works and just uses it, what goes into making each USB generation faster?

At the physical layer, is it the materials in the cables are getting better? Or new ways of using the same materials?

At the protocol layer, is it newly developed computer science theory being applied or is it just old fashioned pragmatic engineering iteration, looking at usage and making the existing protocols more efficient with tricks and shortcuts etc?

Not USB 3.2 Gen 2x2x2?? Come on, consistency people!

It ought to be USB 3.3 Gen 2x2x2, and USB 3.2 Gen 2x2 will be retroactively updated to USB 3.3 Gen 2x2 because everything is always the newest version of USB.

Here's an idea, let's make different connector shapes depending on the cable/connector's capabilities, lets do one for connectors that support display, one for power, one for thunderbolt, that way they're easy for the average consumer to identify!

Oh wait that's the issue USB was supposed to solve in the first place....

Best part is all USB 3 ports get to be rebranded as USB 3.3 as well.
