Whenever the topics of AI and Robotics come up, I always ask: "How much drama do you want in your life?" This type of system does exactly what needs to be done: Get food and drink from the kitchen to the guest. I don't the machine to think or feel, I need it to do stuff like clean the floors (Roomba). Your dishwasher is stationary 'robot' that cleans your dishes. You don't need it to pass judgement on your eating habits. Now, if some bright spark can figure out a system that will do the sorting, washing, drying and folding the laundry that would be amazing. Now there's a challenge for you guys in Silicon Valley!
