$1.5 billion: The cost of cutting London-Tokyo latency by 60ms

That is why there's this neutrinos project
It's not faster than the speed of light though it can shoot through the Earth and no cables cost involved

So far the speed is 0.1 bit per sec

Can't wait for the neutrino SFPs :)

If they could armor the cable sufficiently perhaps they could drill the
straigh line path through the Earth's crust (mantle and outer core) and do
London-Tokyo in less than 10,000km.
