Yeah, this could be great for clustered computing. I only did software for a supercomputer company a while back so maybe there's reasons this wouldn't work, but it seems pretty useful within a rack. It'd probably make people over at [email protected] sad to see those cables go away though.
I don't really see the advantage over a fibre connection myself.
No wires for line of site. No digging, no runs, no fragile expensive tips, etc. That is if and when it stabilizes as a medium.
You then have a communication system that can be shut down by fog or heavy rain though.
It's slightly less stupid in interior applications, but data centre applications will almost always be better suited to wired.
Not really since then all computers share the same link and bandwidth, and latency will be very inconsistent with more than two computers since there will be crosstalk and retransmissions.
With cheaper cables, each computers can max out the bandwidth of each cable, and get much lower latency since there's no crosstalk.
The only benefit is that you don't have to run cables, everything else is worse.
