There are so many choices one could make!
Here is an arbitrary choice of ten that I've read over the years all of which have left a lasting impression. It would be very easy to extend the list.
Isaac Asimov: "Green Patches"
Stephen Baxter: Cilia-of-Gold"
Raymond Z Gallun: "Seeds of the Dusk"
Robert Heinlein: "By Hi Bootstraps"
David Barr Kirtley: "Save Me Plz"
Heather Lindsley: "Mayfly"
Tim Pratt: "Impossible Dreams"
Clifford D. Simak: "A Death In the House"
William Tenn; "The House Dutiful"
"Child's Play"
