Well...drastically simplified, perhaps. :-)

MIMD rather than SIMD? The big advantage of SIMD is that you don't
need N copies of the instruction fetch and decode machinery....

The CA machine I'm thinking of wouldn't even have program counters;
each cell would conceptually be just a blob of combinatorial logic and
a flipflop for current cell state. There may be more state, such as
the 512 bits of RAM I mentioned in a past message, but that's an
implementation detail; conceptually those are control lines.
