X-Message-Number: 13601 From: Date: Wed, 19 Apr 2000 16:19:14 EDT Subject: uploading questions While I greatly admire Yvan Bozzonetti's knowledge and bravura, I think he oversimplifies the uploading questions. For example, he writes, >My own opinion is: "live first" If I have after some methaphysical >questions well, that implies I am living, even as a copy. This begs the question. If someone (natural, artifical, or a hybrid) is living, then that person can refer to himself as "I," but that does not address the question of whether the new "I" is in some appropriate sense the same as the old "I." It does not address the question of whether the original survived. We just don't know enough yet to deal with this, and those who think they do are kidding themselves. He also says that uploading will come before biological nano-repair, because both require the same information but it may be easier to use that information for electronic emulation than for biological repair. There is a great big gulch here. For starters, we KNOW that, now and for the foreseeable future, a simulation or emulation will NOT be fully faithful to the original. The reason is simple. The simulation must be based on current information about natural law, and our information is incomplete and probably in some respects just wrong. The "laws" obeyed by the program are NOT the real laws of nature. Of course, we don't know how important the differences may be, but we cannot just assume the consequences will be negligible. Secondly, biological healing or repair, assisted by nanotech, might easily be simpler than simulation, because we get some help from nature. With simulation, every detail must be present in the program; with biology, some healing/regeneration will occur even if we don't understand it. None of this is terribly important at this juncture, agreed, but we do need to try to keep our thinking straight.
