I think if you try to integrate a structured or O-O knowledge base at the top and a signal processing or neural perceptual/motor system at the bottom, then you are right. We can do a thought experiment to estimate its cost. Put a human in the middle and ask how much effort or knowledge is required. An example would be translating a low-level natural language question to a high level query in SQL or Cycl or whatever formal language the KB uses. I think you can see that for a formal representation of common sense knowledge, that the skill required for this interface is at a higher level than the knowledge actually represented at the top level. If this knowledge was stored in the human brain, then it could be retrieved faster, and by someone who had no special skills in understanding a formal language. But there are still some applications where this design makes sense. One example would be a calculator. At the low level, you have a question like "how many square inches in a third of an acre?" The middle level converts this to an equation and punches the numbers into the top level calculator. This is preferable to the human doing the arithmetic. A database would be another example. Where it doesn't make sense is when the top level is doing something that humans are already good at. It would make more sense to figure out how humans learn and represent common sense instead of guessing. We can do experiments in cognitive psychology.
