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."?

    You forget about error correction, encoding, and line noise on the shitty copper cables. Also the computer at the other end was probably some 8088 POS. Seeing characters float across the screen slower than you could read or type was not common, but it did happen during the late 80's "golden age" of BBSs.

    Actually, I mentioned all of those.

    I remember the echo lagging behind my typing as well, sometimes even on a 14.4 modem - just never because the modem was slow. I suppose the distinction between a slow modem and a slow connection is perhaps a bit pedantic in most conversations, but when we're discussing theoretical bandwidths and the march of technology it seems quite relevant.
