The last computer ever built finds an answer to the last question ever asked.

This is Asimov’s best piece of short fiction, hands down. He thought so, and a lot of people agree, myself included. The story moves through a series of visions of humanity’s future, reasonable and ever expanding until the end, which comes with a literal wallop both terse and mind-blowing. This is a story with deep and important implications, I think, and one of the great classics of science fiction.
