I explained later in my post: limited to the same senses. Also,<br>though, I should have indeed said something like: consisting<br>of a single cerebral cortex. I definitely want to exclude some<br>kind of arbitrary multi-minded computronium-based solution,
<br>because probably no one could argue that *that* would not be<br>possible.</blockquote><div><br>
Well that's the question - senses are easy enough, we already have many
devices for extending those, but are you assuming there's still a
restriction to biological neurons operating at 200 Hz, or are you
assuming molecular electronics at 2 GHz or what? Not that it makes any
difference to the conclusions, but I'm curious about what you meant.<br>

</blockquote><div><br>
Considering that g/cognitive ability are usually defined as performance
on IQ tests, it would be rather surprising if it didn't :)<br>

<br>intelligence, wouldn't you say?</blockquote><div><br>
It's related to intelligence, or rather intelligence is related to it;
if an entity is good at acquiring knowledge quickly, we tend to say
that entity is intelligent.<br>
<br>
It's also, however, related to the rate at which knowledge is available.<br>

</blockquote><div><br>
Chess is a straightforward task, yes. Specifically, of the four levels of difficulty:<br>
<br>
1. NP-hard<br>
2. EXPTIME-hard<br>
3. Incomputable<br>
4. Ill-posed problem<br>
<br>
Simple games like chess don't normally go past level 2; real world
problems tend to be at level 4; so we can't draw too many useful
conclusions from chess.<br>
<br>
Though it does suffice to demolish the idea of a canonical intelligence scale: how intelligent is Deep Blue?<br>

<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">By considering a huge variety of tasks, perhaps it becomes<br>possible to describe a level of intelligence X such that X
<br>is to 200 as 200 is to 180, and then to call that 220. In<br>other words, we take enough samples of tasks demanding<br>cognitive capability, and calibrate our measure accordingly.</blockquote><div><br>
But people with IQs of say 180, greatly differ among themselves in
ability to perform tasks other than taking IQ tests. And that's just
members of H. sapiens with the same basic architecture; the differences
among minds in general will obviously be far larger.<br>

<br>practitioners in the field; they're pretty much in agreement<br>on this.)</blockquote><div><br>
Exactly. <br>
</div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I wish I knew how you are so confident. Are you saying that<br>it's flat out impossible no matter how smart a piece of matter
<br>is?</blockquote><div><br>
Yes. <br>
</div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I must<br>hasten to say that by allowing a week (or a month, whatever),<br>I am supposing that lengthy and costly experiments do not need
<br>to me done, and I could be entirely wrong.</blockquote><div><br>
That's what I'm saying - if you want to solve a problem, you need the
relevant data, which means you need to do the experiments. If you just
make up the data, the results won't correspond to reality. GIGO.<br>
</div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Somehow, it seems<br>strikingly interesting and peculiar if it emerged that no matter
<br>how smart some piece of matter was, all it could do would be to<br>shrug and say "the data simply is not available, and you would<br>have to do the following 26 experiments...".</blockquote><div><br>
Why would you regard it as peculiar that it's not possible to calculate
answers without the required data? Most of the things we want to know
cannot be deduced from the axioms of Zermelo-Fraenkel set theory
because they simply do not logically follow from those axioms.<br>

</blockquote></div><br>
Because the answers we want are not functions or properties of the
information processing system or its internal symbolisms - they are
properties of the real world.<br>
