> After all, what’s faster than the speed of light?
It depends a lot on what material the light is traveling through.
However that is a distraction. The better question is how fast can the carrier (be it: light, RF, x-rays) be modulated. Because it is the speed of changes in whatever property of the carrier is used to transfer information , that is important.
What none of these "Star Trek" technologies consider is the physical interconnects at either end.
The hard lesson from USB, ethernet and all other pluggable, high-speed, connectors is that they are the weakest link - literally: the link. Anything that can eliminate the general crapness, cheapness, vulnerability to crud on the contact(s) and mechanical failings of these connections will get my vote.
