> "Bridgeness" does not translate through the levels.<br></blockquote><div><br>A brick bridge does not translate through levels but the abstract concept of bridgeness translates beautifully. We also know for a fact that arithmetic translates through the levels and the exact same thing is true for all of mathematics, and literature, and music, and the digital genetic code, and intelligent behavior.<br>

I don't. <br>

</blockquote><br>Just like a calculator might find it possible to create the appearance that 2+2=4, but that is just a simulated answer using simulated arithmetic; if you want a real answer you can't use a calculator you must work it out yourself using real arithmetic, only then will you know how much 2+2 is.<br>

</div><br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote"> > Simulations are, after all, only simulations.<br></blockquote><br>Yes I can't argue with that, simulations are simulations. <br>

</blockquote><div><br>All literature every written in any language is also digital, every single word, so is arithmetic, so is music both in it's written form and on your iPod, movies too . The genetic code that makes you the man you are today is also digital.<br>

> I also understand the architecture of digital computers well enough to look at them and see that whatever makes this thing I call consciousness, it sure does not look like a digital computer can do it. <br></blockquote>
<div><br>And what in hell would a thing that COULD produce consciousness look like? We both know the answer to that and mind architecture be damned; I have read enough copies of your messages to understand that you don't think digital computers can be conscious for one reason and one reason only, they are not soft and squishy. If you have a more profound reason than that you have never mentioned it. <br>

Just not a digital one.<br>
</blockquote><div><br>Back in 1995 Marvin Minsky was on this list, he invented the confocal microscope and many consider him to be the father of AI; Isaac Asimov, a man not noted for his modesty, said that in his entire life he only met 2 people more intelligent than he was, one was Carl Sagan and the other was Marvin Minsky. Anyway, in 1995 Minsky expressed contempt for: <br>
<br>"people who happily assume that analog computers bring some mysterious sort of infinite precision that cannot be simulated by a mere 64-bit computer working with double precision floating point. I used to use analog computers, [...] If you were real careful, even at Room Temperature, you could sometimes get close to 10-bit performance for brief periods."<br>
<br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">> If you think consciousness follows necessarily from brain-like behavior then I suppose you must think some computers are already at least semi-conscious. <br>
</blockquote><div><br>That would be a reasonable assumption if you thought that intelligence is a much much richer problem than consciousness, and that is exactly what I believe; I don't see how else you can explain the fact that half the people on this list have some tin pot General Theory of Consciousness, but not one has even a bad General Theory of Intelligence.<br>
<br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">> Brains are not like digital computers. <br></blockquote><div><br>I know, brains are squishy but digital computers are not.<br>
</div><br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">> Brains are biological organs, not fundamentally different from livers or kidneys.<br>
</blockquote><div><br>Yes, all those organs have one thing in common, squishiness.<br><br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">> Some clever programmer will one day write a program that passes the Turing test. I might be fooled into thinking it is actually conscious. <br>
</blockquote><div><br>This question should have been settled to everybody's satisfaction in 1859 and why people keep blabbing about it is a great mystery to me. It's a fact, if the Turing Test doesn't work for consciousness because intelligent behavior and consciousness are not related then Charles Darwin was dead wrong. I do not think Charles Darwin was dead wrong. <br>
<br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">> those parts of the brain that correlate to consciousness [...]<br></blockquote><div><br>If there are parts of the brain that correlate to consciousness and nothing else, if there really is something that Robert Ettinger called a "consciousness circuit" then Charles Darwin was dead wrong. I do not think Charles Darwin was dead wrong. <br>
<br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">> Do you believe the world is *intrinsically* digital<br></blockquote><div><br>If time and space are quantized then the world is 100% digital, there are good reasons to think that they are but we don't know that for certain. But we do know for certain that the things we care about the most ARE digital, like literature and music and movies and our genetic inheritance. And even you admitted that a digital computer might behave so intelligently that you could be "fooled" into thinking it was conscious, so intelligent behavior is digital too. And so unless Charles Darwin was dead wrong consciousness is also digital. I do not think Charles Darwin was dead wrong.<br>
