Grandpa: Timmy, you’d better do your homework.
Timmy: I don’t have any homework grandpa, not since mom bought the neural inductance educator.
Grandpa: I don’t like you gallivanting about with those Bravaxians. Mark my words, they’re a bad influence.
Timmy: I don’t have to listen to you. You’ve been dead for almost a whole year now, and the service contract on your ghost is going to be up soon. You won’t be so bossy when your projector drone is packed up in the closet.
The Eternal You Life Extension Group started offering services in the last decades of Era-0. Their most popular service was the Ghost System that would upload a complex simulation of the subject’s personality into an artificial intelligence system coupled to a holographic projection system. The Ghost System was installed in a drone or (less expensively) in a particular location, often a residence. The subject would buy an initial service contract (often for a year), with the option for extension going to the inheritors of the deceased’s estate.
