Would you be happy to share everything about yourself if the trade-off was kind of like owning that computer that runs the show in that 80's classic 'Electric Dreams"? (O.K, maybe not exactly like that). His dalliance with the data has done some things like search his calendar, find a glitch in his travel plans with a late flight and tell him to sleep in instead of head to the airport.
