In the broader sense of terminal, I don't disagree. I was
being somewhat clumsy in talking about terminals in
the Plan 9 sense of the processing power local to my
fingers.

Maybe, and maybe what we ought to look at is precisely what Plan 9
skipped, with good reason, in its infancy: distributed "core"
resources or "the platform as a filesystem".

even today on an average computer one has this articulation: a CPU (with
a FPU perhaps) ; tightly or loosely connected storage (?ATA or SAN) ;
graphical capacities (terminal) : GPU.
It happens so that a reversal of specialization has really taken place, as
Brian Stuart suggests. These "terminal
