The physics is not conducive to improving the situation a lot. There's probably $1.5 billion in the ground already in neutrino detectors; the total combined detector bit rate is pretty poor. One experiment looking at neutrinos coming off the Fermilab accelerator had 473 million accelerator pulses with under 1.1 million detected neutrinos.

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
I bet for $ 1.5 billion neutrino communication (anywhere on Earth) to its antipode in about 40 msec one way) could be developed (i.e., the bit rate improved), and I could see some real market advantages to anyone who had access to it, even at 100 kbps type bit rates.
Given that, I wouldn't be too surprised to see some physicists and networking people quietly being hired away by an obscure new venture...

Can't wait for the neutrino SFPs :)

All three cables are being laid for the same reasons: Redundancy and speed. As it stands, it takes roughly 230 milliseconds for a packet to go from London to Tokyo; the new cables will reduce this by 30% to 170ms. This speed-up will be gained by virtue of a much shorter run:
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.
