[comp.ai] AI seen as an experiment to determine the existence of reality

simon@comp.lancs.ac.uk (Simon Brooke) (06/09/88)

Following the recent debate in this newsgroup about the value of AI, a
thought struck me. It's a bit tenuous....

As I understand it, Turing's work shows that the behaviour of any
computing device can be reproduced by any other. Modern cosmology holds
that:
	1] there is a material world.
	2] if there is a spiritual world, it's irrelevent, as the
		spiritual cannot affect the material.
	3] the brain is a material object, and is the organ which largely
		determines the behaviour of human beings.

If all this is so, then it is possible to exactly reproduce the workings
of a human brain in a machine (I think Turing actually claimed this, but I
can't remember where).

So AI could be seen as an experiment to determine whether a material world
actually exists. While the generation of a completely successful
computational model of a human brain would not prove the existence of th
material, the continued failure to do so over a long period would surely
prove its non-existence... wouldn't it?

Your argument was pretty slipshod.  I for one do not believe the above
is even possible in principle.
