1) One can control only what it perceives - this is today
a tautology for modern AI robotnics, and at first instant
they don't understand what's the big deal.
I think they get the idea that perception is involved in control
(that idea has been around since Descartes) -- but I have never
seen any sign (in modern or old- fashioned AI robtics) that
control is the maintenance of perceptual signals at a reference
levels. Any examples of AI-robotics models _explicitly_
(not accidentally) based on control of perception would be greatly
appreciated (these should be easy to find since control of
perception is a tautology in the field).
Concerning the specific research issues that Michael raised,
it seems that it might lead to areas of controversy concerning
higher-order entities such as organizations. What is a factory
controlling for? Should every perceptual variables of the factory
be encoeded using one transmission line ("one neuron for one percept")
or should they be distributed in time and space?
Where are the receptors that produce the perceptual signal
carried by the transmission line(s)? Is there a big transparent
retina hangling over the factory deriving perceptions of things
like "productivity" and "team spirit"? Where do the perceptual
signals carried by the transmission lines go? To the big
"organizational control system" in the sky (up there above
the transparent retina).
I think some research issues can be ruled out as issues before
anyone starts asking for funding.

Sometimes I think you're being too rigid and hard-headed, but
almost every time you manage to convince me that you're right.
Yes, the perceptual signal is controlled, and no, it does not
Born to be a thought policeman.
Convincing you I'm right about PCT "almost every time" is WAY
more than enough for me. Thanks.
