Lovely dream. It is unfortunate that it takes 130ms (10x as long as your dream) for a pulse of light to circumnavigate the world. Even if it was point to point, without switching or network delays, it would take up to 60ms.

You can't remove the speed of light constraints, no matter how nice it would be.

There's a saying: bandwidth is money; latency is physics.

You can always get more bandwidth (more flow per second) through the pipes by just building more pipes. This isn't difficult, just expensive.

Reducing latency, however, is much harder. Eventually you still have to deal with a photon moving through fiber and an electron and a circuit.

Thanks for the reference. I appreciate it.
