Time for another episode of the podcast, and this time we delve into our favourite sci-fi artificial intelligences.

We  largely ignore ambulatory A.I., so you won't find much talk of robots  or androids here. Instead we try (but don't always succeed) to discuss  the type of A.I. that won't chase you down a corridor or strangle you.

Among the works mentioned are some Star Treks; some Keith Laumer, Asimov, Clarke and Gerrold; and several classic movies that highlight our human terror at the thought that computers might one day take over.

Read more about science fiction's use of artificial intelligence in the Encyclopedia of Science Fiction and the Historical Dictionary of Science Fiction.
