"Every sufficiently-complex system eventually includes a badly-implemented email / lisp / kafka (/zmq/etc)" Something like a combination of Greenspun's Tenth Rule[1] and Zawinski's Law[2]. Plus whatever would include your queueing system of choice. Though honestly I've seen more bad queues than emails or lisps. By an order of magnitude or two.
