Better than Blackboards

(Warning, there really is not much evidence for this slide)
A lot of big systems use a blackboard to communicate between modules because blackboards are a nice way of communicating information between modules.
CAs manage that communication by millions of synapses.
The communication is context sensitive.
The CA-model is better because the developer does not have to set up the modules and their communication.
The communication emerges from the architecture.
This means that connections can be made, that are usually unimportant but in certain circumstances are critical.
CAs support a less modular design that works due to learning.
