Last time I looked spectrum was still a valuable resource,
protected by legal enforcement. There should be room for low-power
spread-spectrum grass-routed cellular which looks indistinguishable
from noise (remember CryptNet?), but such infrastructure needs
a minimal coverage threshold to be interesting and its hardware be
a commodity item to be affordable while being violently opposed by
telco and information provider oligopolies. Also, we need something
along the lines of ATM for a matrix, while distinctly suboptimal
TCP/IP still reigns supreme.
That HDTV is very dead I certainly can agree with. As to streaming
video, the global bandwidth is not yet adequate. Unless arrested at
protocol level (pay by packet), xDSL will push further bandwidth
clogging, and thus will require a yet another networks upgrade.
And after streaming video there will come a yet another resource
hog, I am certain.

Have you noticed that both VR/AR and HMDs are ailing, as does the
magickal wearable? Such a coincidence. According to the wear-hard
list, several novel HMDs are in the pipeline, but then, they are
in the pipeline for half a decade at least. Boooring.

DSPs don't have virtual memory, which most Linux flavours require.
A multiple-DSP machine needs a message-passing nanokernel
architecture, which Linux certainly ain't. Instead of using multiple
processors, possibly on-die, there is still a fatal
(software-artefacted) trend towards monolithic monster
processors to be observed, whether vanilla PC or DSP.
On the long run, OSses are obsolete, anyway. On the really long run,
even the difference between software and hardware will be nivellated.

With a high-speed wireless modem can do that with a wearable, today.
A receive-only unit is not flexible enough by far. Moreover, watching
movies while crossing street does not exactly appear to be a healthy
occupation.
