Huh?<br><blockquote type="cite"><div><br></div><div>the event itself does not equal a computation.</div></blockquote><div><br></div>That depends entirely on what the "event" is; if it involves moving atoms then Swobe is right, but if it involves things other than nouns or in making decisions then he is not.<br><blockquote type="cite"><div><br></div><div>Anybody who says "A digital simulation of a brain will equal a brain" says exactly that a computation of x = x where x = a brain.</div></blockquote><div><br></div><div>Swobe trots out this sad old straw man yet again! Of course a simulated brain is not identical with a biological brain, but a simulated mind is, just as a simulated 4 (whatever the hell that means) is identical with a real 4. </div><div><br></div><blockquote type="cite"><div>Except in the special case in which x = a digital program or computer, the digital simulation of x will not even look like the originals</div></blockquote><div><br></div>Except for that Mrs. Lincoln, how did you like the play?<br><div><br></div><blockquote type="cite"><div>the man in the [Chinese] room has no access to sense data from the outside world</div></blockquote><div><br></div>Yet another reason why the Chinese room just may be the most useless thought experiment ever devised; a real AI would certainly have sense data about the outside world, far more the we do in fact.<br><div><br></div><div><div><font class="Apple-style-span" color="#000000"><blockquote type="cite">when we look at how computers get sense data, we see that sense data also amounts to nothing more than meaningless patterns of 1's and 0's.<br></blockquote><br>One can't help but wonder why Swobe doesn't erase the hard drive on his computer, it is after all full of nothing but a meaningless pattern of 1's and 0's. It's also puzzling how Swobe makes a living, he says he does it by generating patterns of 1's and 0's, but who would pay him for such a meaningless activity?</font></div></div><div><br></div><blockquote type="cite"><div>go find your magnifying glass and take closer look at that apple on your monitor.

It's a pity Swobe didn't say that two months and several hundred posts ago, think of the time we could have saved.
