SOLVED. Adult Science Fiction. Robot butler so faithful that he maintains the house after the residents die off...and after all humanity dies off. [s]

[Brian]

Short story, read in the 90s, though could be older. A robot servant is so faithful to his masters that he maintains their house after the family dies off, after all of humanity dies off, after the other robots build ships and leave for the stars, after dogs evolve to become sentient and leave for the stars themselves, after the ants take over the world (except for the house the robot maintains), after the ants die out...only when the robots return from space and ask him to join them in their colonies does he finally accept that he can leave.

Is it one of the City stories by Clifford D. Simak? City

[Sue]

Totally agree this is City. It's a book of linked stories, and the robot "Jenkins" is in nearly all of them.

[Brian]

The name Jenkins rings a bell. I think you're both right.
