But as for this week, has it ever been established how long a doll can be programmed? Could Adele's dead friend, for example, have lived another entire lifetime inside Echo's body? (I know that Adele wouldn't have allowed it, but if the technology allows it, eventually it's going to be possible.) I remember them making a point about how multiple downloads of the same personality into the same doll on a regular basis is a bad thing, but I can't remember if they've established an "upper limit," time-wise, for how long a doll can "run" on a given program.
