They lost me at "our conductors are coax!". USB is designed around differential signaling, which is what twisted pair excels at.

Twisted pair is good but it only gets your losses so low at these speeds. Keep in mind that USB cables have a very small budget for signal loss, and at 40Gbps they're carrying frequencies 25x higher than 10gig ethernet.
