Moving the Goal Posts and Artificial Intelligence

From Mind Hacks:

Mind Hacks: Minsky slams modern AI: [Marvin Minsky makes] a throwaway comment about the 'moving goal posts' problem in the perception of artificial intelligence, that belies much of the problem with how AI is perceived.

It is illustrated by the success of chess computers. In the 60s, it was said that computers will never beat people at chess, because that requires intelligence and computers aren't capable of intelligent thought.

When computers regularly started winning matches in the 80s, it was claimed that playing chess wasn't a test of real intelligence because computers could do it.

As there is no widely accepted definition for intelligence, this is often an example of the No true Scotsman fallacy.
