Recently I got 400 megabit/second on my cheap cellphone through a friends WiFi out to the Internet. That's more than 100 times the speed of ArcNet[1], the first networking system I worked with.<p>Sure, the maximum numbers are based on almost ideal conditions but we'll get there soon enough. There will be further advances in technology, likely optical. I fully expect that a Terabyte/second will seem slow in a decade or two.<p>[1] <a href="https://en.m.wikipedia.org/wiki/ARCNET" rel="nofollow noreferrer">https://en.m.wikipedia.org/wiki/ARCNET</a>
