>the intelligence is not in the transducers, so it must be in what is
left.

I don't think this has been demonstrated. If the sensory organs do
sufficiently complex processing, the possibility remains that intelligence
is distributed between them and the brain. The practical experience that
underlies this is an advanced submarine combat system where there are at
least three major layers of processing, all of which are required for the
system to function "intelligently." The first layer is the sonar proces-
sing, which is responsible for feature tracking. The second layer is target
motion analysis, which is responsible for associating features to specific
targets, creation of new target tracks, detection of target course
changes, and maintenance of target states. The third layer is engagement,
which in many ways is similar to frontal cortex processing.

Note that there are quite a few operators embedded in this system, some of
whom have the specific role of applying their judgement. As an overall
system, it behaves "intelligently," yet any specific component is less
than intelligent, since processing by other components is needed for
overall function.
