I am convinced that a Siri-like interface could (with existing or almost-existing technology) tap into the writings of a deceased person and answer questions shockingly well - questions from loved ones to start, but even from people 1000 years from now. Especially if the deceased person had been planning and recording anticipated questions for a year or two. What better way to preserve yourself for posterity? You could charge a million dollars and still get plenty of customers today - even if you told them it wouldn't be possible yet for years. I remember listening to old audio of W. Clement Stone saying the way to sell life insurance wasn't to convince the person that it would take care of their family once they were gone, but to tell the person that it was the only way to continue to control their family and direct their finances after they had died. People have an urgent need to retain some type of control, and they know without their help their family would certainly make poor and unwise choices.
