Well, it's been newn... I mean known since computer networks were invented that it'll take them a long time to match with a throughput of a train carrying recorded media. The point is that throughput is not the only important parameter: the other is response time...

Guinness World Record breaking, "first radio amplifier operating at terahertz frequencies could lead to communications systems with much higher data rates, better radar, high-resolution imaging that could penetrate smoke and fog, and better ways of identifying dangerous substances, say the researchers who built it".
Built from HEMTs (High Electron Mobility Transistors) made of InP (Indium Phosphide), this is a new milestone on the road to the THz applications.
