Classic SF

The Last Question is a seminal short story by Isaac Asimov that informed my early perception of science fiction as a genre. Its the first SF story I can clearly remember reading and going, "Wow!" at the end.

It's a little dated, what with the presumption that BIG computers of the ENIAC/UNIVAC variety would be standard millions of years into the future. But if you just read "Internet" everywhere you see a reference to one of these "Analog Computers" it holds up just fine.
