[arin-ppml] debunking the myth that Moore's law helps

I wonder how much b/w to the home is actually needed and if there is a
natural demand "limit". It seems to me that once b/w to the home reaches
realtime HD video there's not really much more that is required (except
for separate channels for the kids, of course). If you think about it,
there's only historically been two drivers for b/w throughout the
history of communications. Ignoring the original low b/w uses, morse
code, teletype, etc, we have realtime voice and realtime video. For 80
years, video has stabilized at about 3 Mhz b/w and it's only with the
advent of HD that we have exceeded that (is that true? I'm not sure,
considering compression and all).

Is it really reasonable to expect future b/w demands to the home to keep
going up and up? What drivers do you see for this?

Just curious.
