“Why are we so far from the speed of light?“ Because we don't know how to build an optical router with the same capabilities as the ones we use today and the alternative is to give up on net neutrality. I'm ignoring endpoint performance and protocol bloat. There is work being done in quantum computing that might eventually lead to some CPU like device operating on photons alone and hollow core fiber optics also seem to be an active field. The work on upgrading the various protocols together with limiting network requests seem to be the way to go until our technology catches up.
