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....
