I think this will be the way towards general intelligence, multiple decentralized 'brains' working together. For example, you may have something that processes vision, something that does task planning, something that does motion planning, something that processes audio, etc. One day we will bring these parts together into single systems, but for now it's much easier to train and test these independent 'brains' until we figure out a proper architecture. There are quite a few different things we need to answer, for example, can motion planning and motions be de-coupled? Can vision detection be de-coupled from object classification? Can hearing be de-coupled from vocalization?
