The Loebner Prize for artificial intelligence is the first formal environment -- sweetened by a $100,000 prize -- to attempt to conduct a Turing Test, a test of a machine's ability to exhibit intelligent behavior.
The thinking goes like this: if a computer's responses are indistinguishable from those of a human, the computer is said to be able to think.
Judging by the latest attempts, the human race is safe -- for now.
In the spirit of the challenge, researchers at the Creative Machines Lab at Cornell University thought it interesting (amusing? revealing?) to have two such machines, called Cleverbots, conduct a conversation -- with each other.
