Aquantia 10GBase-T TB3 self powered, adapters are now available. They
support 803.11bz.

Again it's not the speed, it's the throughput. TB3 delivers near to
what my local x86 can do in terms of throughput. Also network should
never be slower than disc. Since NVME has been around this is
no-longer true. It's an unnatural order of things.

Interestingly the NVME stuff came about by a competing teams during
the same time as Lightpeak. They share many underlying philosophies.

Cabling is the issue in my mind right now. Every laptop with tb3 ports
has 10G+ capability, if passive optical long run was cheap and easily
available for tb3 then half the problem would already be solved.

Maybe 10G over cat6a will be ok as the evolution. But you have to go
to cat8 to get anything beyond 10G... so the cabling situation and
incentive to upgrade to future-proof isn't there.
