I don’t need to know much about the ebb and flow of robot activity. They can certainly make for varied and interesting conversationalists but I hesitate to dig deeper in an attempt to learn more about their inner lives. In a way they are very much like the cats they keep company with: somewhat inscrutable and revealing only what is necessary in the moment. Still waters may run very deep indeed. (Upon my first use of this metaphor in a conversation I had to go to great lengths to explain that puddles may be still indeed but they weren’t always deep. Unless they were!)
