Haven't read the whole paper yet, but below 600 Mbit/s is implied as being "Slow Internet" in the intro.

Meanwhile, low-end computers ship with a dozen 10+Gbit class transceivers on USB, HDMI, Displayport, pretty much any external port except for ethernet, and twice that many on the PCIe backbone. But 10Gbit ethernet is still priced like it's made from unicorn blood.
You really can’t think of any major difference between 10G Ethernet and all of those other standards that might be responsible for the price difference?
Look at the supported lengths and cables. 10G Ethernet over copper can go an order of magnitude farther over relatively generic cables. Your USB-C or HDMI connections cannot go nearly as far and require significantly more tightly controlled cables and shielding.
That’s the difference. It’s not easy to accomplish what they did with 10G Ethernet over copper. They used a long list of tricks to squeeze every possible dB of SNR out of those cables. You pay for it with extremely complex transceivers that require significant die area and a laundry list of complex algorithms.
No matter, eventually USB4NET will work out of the box. The USB-IF is a clown show and they have tripped over their shoelaces every step of the way, but consumer Ethernet hasn't moved in 20 years so this horse race still has a clear favorite, lol.

Meanwhile a 10g port on my home router will run over copper for far longer. Not that I’m a fan given the power use, fibre is much easier to deal with and will run for miles.
