Listening to Diamandis and Kotler's "Abundance" in the car. They were just talking about how AI would let robots take better care of old people. It seems to me that fulfilling the aged and infirm's basic functions is not the issue. It is having someone there to love, care, and be present for them (see Gawande). To the extent that robots can feed and clean and allow family members to do the important stuff, it's good. Otherwise the technology is just a way to allay guilt of not being there for loved ones.
