Science Fiction Predictions, or, 2001: No Space Odyssey
This is an extension of the conversation in the comments section of "Worst Movie Endings" over my distaste for the movie 2001: A Space Odyssey. My conclusion: first third (Apes) terrible, middle third (HAL) okay, last third (LSD trip) horrific. Anyway, the point of this post is to pose a question.
2001: A Space Odyssey was written about the year 2001 (12 years ago now!) and predicted that space travel would be fairly common, with large space stations in orbit and a manned mission to other planets. In addition, Arthur C. Clarke predicted an artificial intelligence in the form of HAL, the ship computer.
The reality is that we haven't gone back to the moon, and, although in some ways we have more advanced computers than HAL (i.e., much smaller, with better visual interfaces), we haven't really achieved AI that can carry on a conversation.
For a human conversation I pose:
Science fiction predictions. Who has been the most accurate? Where has science fiction been over-optimistic? Under-optimistic? And we don't have to restrict this to science fiction, e.g. Ray Kurzweil.
