There are apps that stress 1 Gbps - they require interactive surfing of
high-res (100M pixel) images. The best digital cameras do 1/10 that, and
the best displays are 1/25 that. I'm not saying never ever - I'm saying
we're  not there yet (gigabits are currently needed only where apps are
broken in the wrong place). Plus you need someone who wants to do that
surfing, nearly continually and unpredictably.

What we need, overall, is high bandwidth unpredictable interactivity -
that's what the paper says stresses BW, and it's just as true today.

What the paper says, and I also stand by, is that most uses of 1 Gbps
are apps broken in the wrong place to showcase the need for BW.
