``In considering any new subject, there is frequently a tendency first to overstate what we already find to be interesting or remarkable; and secondly by a sort of natural reaction to undervalue the true state of the case when we do discover that our notions have surpassed those that were really tenable.''
When will we know when we have made it?
Turing suggested in his article, 'Computing Machinery and Intelligence' (1950)
that a truly intelligent machine will become indistinguishable from a human
in conversation. He proposed to demonstarte this via an interrogation test whereby
an interrogator would set questions to be answered by a human and a computer,
both attempting to prove themselves as the human. Printed copies of their responses
would be returned to the interragator, when the machine could not be reliably
identified it would be truly intelligent.

The following questions suggest what we require.
Is the task clearly defined?
Is there an implemented procedure for the task?
Is there a set of regularities or constraints from which the procedure derives its power?
Is the procedure generic?
Does it degrade gracefully in the presence of noise?
Recently Newell suggested the following attributes for an AI system :
operates in real time
exploits vast amounts of knowledge
tolerates errorful, unknown and unexpected inputs
uses symbols and abstractions
communicates using natural language
learns from the environment
exhibits adaptive goal-oriented behaviours
