USB 3.2 Gen 2×2 isn't even my final form:

Fulfilling its 2017 promise to make Thunderbolt 3 royalty-free, Intel has given the specification for its high-speed interconnect to the USB Implementers Forum (USB-IF), the industry group that develops the USB specification. The USB-IF has taken the spec and will use it to form the basis of USB4, the next iteration of USB following USB 3.2.

Thunderbolt 3 not only doubles the bandwidth of USB 3.2 Gen 2×2, going from 20Gb/s to 40Gb/s, it also enables the use of multiple data and display protocols simultaneously. We would expect the USB4 specification to be essentially a superset of the Thunderbolt 3 and USB 3.2 specifications, thus incorporating both the traditional USB family of protocols (up to and including the USB 3.2 Gen 2×2) and the Thunderbolt 3 protocol in a single document. Down the line, this should translate into USB4 controllers that support the whole range of speeds.

Lost? Frightened? Confused? Good!

    I don't really care about 5G or 6G or 20G or 150TB/s, for anything like that I'll use mSATA/M2/whatever or ethernet and not some serial port on steroids. What I really want in USB is a single connector and the ability to plug A into B and it'll just work. I'd actually go back to 12Mbps USB just to have the ability to plug things in and have them work without having to piss around with drivers and cables and different settings and adapters and converters and hubs and then half the time it still doesn't work.

    In other words, to the USB consortium, concentrate on making what you've already got actually work properly before you start wanking around with USB 3.2.4.1 revision 2 patchlevel 4 with mustand and anchovies.
