Oh of course, I didn't want to go into that detail but trust me I know all that, TB3 got donated to USB IF, it became USB 4 with a few extras (most importantly the USB packets on the bus). And then Intel took USB 4 and put a marketing name on "USB 4 with every optional feature on" and called it Thunderbolt 4.
And yes, likely next year, AMD will have USB 4 but -- not right now.
And the problem is not exactly the bus speed -- although 10Gpbs is not that much -- but the lack of external PCI Express (or any other DMA capable protocol but the last non-PCIe tech doing that was Firewire and that's gone).
