The first metaphor implies that a computer performs some tasks in similar ways to how our brain processes external stimuli.

Nope. Don't agree. Don't think a digital computer processes external stimuli in any way similar to my brain. First thing a computer would need is a reticular formation to filter the thousands, if not millions or more, of simultaneous sensations and perceptions I'm exposed to at any given instant. Evolution gave me one, we dunno how to give a computer one. We ain't digital so I find that metaphor every bit as weak as its converse. Wink

That isn't the case. We aren't trying to make our brains more like computers, we are trying to make our computers more like brains.

On that we agree. The Holy Grail of AI is to make a computer which at least observably functions indistinguishably from a brain regardless of its underlying systems and structure. We want to make a machine which can pass the Turing Test. ... Why? 'Cause we technologists now. Thumbsup

And shouldn't you be carbon dating some fossil or something? Who let you out of the lab? Big Grin
