Just two systems is too simple, too naive. The Society of Mind by Marvin Minsky is a must read for anyone who is trying to speak about AI. The notion that there are quick and slow systems are old one - reflexes vs. recognition is the simplest example - recognition is too slow. But there are not two or three systems, there are.. I cannot say how many, but if we believe that we have a distinct "subsystems" to recognize eyes, and mouths and faces by matching some cues, there must be vast hierarchies of such sub-systems (agencies in Minsky terminology). So, some processes (agencies) are "slow" some are "fast", some works with quick-and-dirty data, such like a sudden motion catches our attention, before we're able to recognize what's going on.. The notion that each word we see does some "priming", pre-fetching in CS terms leads to the vastly complex view of how even seemingly simple tasks are performed. So, all we can do is to recognize familiar (known in advance) patterns and look at its weights as modern computer translation services do.
