In the form of usage that is needed for combining AI and control systems
to obtain autonomous intelligent systems, it is important to recognize
that the pointwise descriptors and indicators must eventually take on
the characters of symbolic expressions that exist in a language of
non-trivial complexity.  In relation to this purpose, it does not
really matter if their information is viewed as represented in
the states of discrete machines or in the states of physical
systems to which re
