IMHO expert systems share an Achilles heel with programming languages. They're
both limited by the number of lines of code that can be maintained. Once they
reach about a million lines of code, my understanding is that its too unwieldy 
to maintain or debug. Thus a million lines of code is the "glass ceiling" for
now.

On a more positive note, research into machine learning is addressing this 
limit.
