The dog's remote control is the whistle. :) I expect that at some point the utility of the robot/drone will outpace the utility of the dog in this role (and others). Wanting to hang on to our dogs isn't a bad thing, but I don't think we will be able to make as many arguments based on their utility. Instead we'll just have to accept the idea that the reasons for having them (and even working with them) will be cultural/emotional instead, which are perfectly good reasons. We have an Australian Shepherd as a family pet - they're amazing companions!
