The late Stanley Kubrick's film 2001: A Space Odyssey portrayed a computer, HAL 9000, that appeared to be a conscious entity, especially given that it seemed capable of some forms of emotional expression. This article examines the film's portrayal of communication between HAL 9000 and the astronauts. Recent developments in the field of artificial intelligence (AI) (and synthetic emotions in particular) as well as social science research on human emotions are reviewed. Interpreting select scenes from 2001 in light of these findings, the authors argue that computer-generated emotions may be so realistic that they suggest inner feelings and consciousness. Refinements in AI technology are now making such realism possible. The need for a less anthropomorphic approach with computers that appear to have feelings is stressed.
