Yes, intelligent design is an outcome of a grander process and can never surpass it. Intelligence is always going to be bounded by the process that produces it.
Intelligence is the cause of the evolutionary process...not its outcome. Just as Artificial Selection is the cause of several kinds of dogs, horses, cows, plants etc. And just as human Intelligence is the cause of computer, car, plane evolution and development.
We just can't see and understand the Intelligence that produces us because we are its products and we have severe limitations.
