That sounds overly binary to me. (said with conscious irony) You are saying that the informational inputs and outputs for walking robots have exactly the same amount of relevance to biological limbs and biological control of walking as the engineering of steam locomotives? Obviously they have aspects that are nothing like walking creatures. But the more they solve the same problems, the more they have to be similar, either intentionally or accidentally.
