As reported at C|net, USB4 is ready to go.

USB4 is done, the group developing the next version of the immensely successful USB connector technology said Tuesday. USB4 doubles speeds compared to today's fastest USB 3.2 by incorporating Intel's speedy Thunderbolt technology that you already see on high-end laptops and peripherals. The USB Implementers Forum announced the completion of the technical specification Tuesday, a move that frees hardware and software engineers to get cracking building the actual products to support it.

Today's USB 3.2, which enables data transfer speeds up to 20 gigabits per second, is still something of a rarity; most of us have earlier versions of the technology that works at 5Gbps or 10Gbps. USB4 promises a speed boost to 40Gbps, helpful for things like using multiple external displays or fetching files from external hard drives.

What is the Serial Bus equivalent of, "Looks like I'm going to have to buy the White Album again."?

    Will this mean usb4.1, usb 4.1.3, usb 4.1.35, each with different characteristics for different manufacturers of ports and displays?

    Or did they get it right the first time?

    Because usb 3/thunderwhatever has been a collosal fuckup that should have shaken everyone in the world's confidence in humanity to produce any standard whatsoever, meaning progress went backwards in a sortof big way.

    50 years from now there are going to be people trying to get usb 3 things to work and looking for the rare cable they need to access a device manufactured in 2014.

    A thousand years from now, they are still going to be using usb 2.0, because that shit just works. If I were building a spaceship I would make all of the interconnections usb 2.0 just because I know when I'm in space I will sleep well. If I knew there was a single usb 3.0 device in my spaceship, I wouldn't be able to sleep until I had ripped it out.

    It's pretty bad, but I think Bluetooth 5 might be shaping up to be worse. The best features are optional, an old ass mandatory audio codec is still in use with no Opus.

    With USB, a hybrid cable delivering the max data rate and all the power the spec is rated for would solve (almost) everybody's problems. It's just that it would be too expensive I guess.

    When USB 4.1 comes out, they will retroactively rename USB 4.0 to USB 4.1 Gen a1 mk II
