Get rid of the "older" in the whole idea and you're onto a social issue that needs addressing. But like any other social issue, this cannot be solved by technology, even if loudmouth tech morons like to pretend otherwise for that sweet sweet public funding. To quote Douglas Adams on the whole robot idea:<p>"The Encyclopedia Galactica defines a robot as a mechanical apparatus designed to do the work of a man. The marketing division of the Sirius Cybernetics Corporation defines a robot as 'Your Plastic Pal Who's Fun to Be With'. The Hitchhiker's Guide to the Galaxy defines the marketing division of the Sirius Cybernetic Corporation as 'a bunch of mindless jerks who'll be the first against the wall when the revolution comes'."
