That is a good counter example, although it comes with some caveats. I work
with SS7 regularly. SS7 should be simple since it performs a simple
function, it is actually complicated and complex. But, since SS7 takes us
away from the human-managed "static routing" of the older (MF?) trunk
networks systems, it's intelligence creates redundancy and limited failover.
Perhaps Clark will create something that is win-win like that...
(I assume you are giving this as a "intelligent vs. simple"
counter-example, since SS7 is an example of good scale because it trusts
blindingly.)
