This guy most know something about the speed of light that Einstein didn't. Unless he's managed to construct space/time worm holes in a data centre, then he's going to have to put up with the same 300 metres per microsecond propagation speed as the rest of creation. Of course that's if he's found a way to route photons through a vacuum. Signals via copper or fibre don't go faster than about 200 metres per microsecond, which means that 50 metre link is never going to have a round-trip time less than 0.5 microseconds, whatever you do with switched, adapters and the like.
There are very low latency interconnects of course, but they all have very short reach for this reason. Indeed the propagation speeds inside computers are a fundamentally limiting factor, let alone on external comms links.
