Actually, vision is higher bandwidth than that - most VR people estimate that approaching human vision requires a gigapixel/second (at 24 bits or more per pixel) - and even that needs to play lots of eye-tracking games to concentrate the rendering on where the eye is focused. Consider how fast even high-end NVidia cards can pump out pixels and you can *still* see it's CGI. Well-shot 4K video of real objects displayed on a good monitor is *just* reaching the "it actually looks real" level - and that's a hell of a lot more than 4Mbps. And remember that bits are consumed by more than just one human per dwelling - you can have multiple people watching different things, and silicon-based consumers burning lots of bandwidth on behalf of their carbon-based masters. There's about a half-zillion ways a gaming console can burn bandwidth, for example. Heck, the Raspberry Pi under my TV can soak up more than 4Mbits/sec just doing a software update. /me makes popcorn and waits for 4K displays to drop under US$1K and watch the network providers completely lose their shit....
