Another great short story. You can listen to this here or read it online here.

By Asimov’s words:

“This is by far my favorite story of all those I have written.
After all, I undertook to tell several trillion years of human history in the space of a short
story and I leave it to you as to how well I succeeded. I also undertook another task, but I
won’t tell you what that was lest l spoil the story for you.
It is a curious fact that innumerable readers have asked me if I wrote this story. They
seem never to remember the title of the story or (for sure) the author, except for the vague
thought it might be me. But, of course, they never forget the story itself especially the
ending. The idea seems to drown out everything — and I’m satisfied that it should.”
