X-Message-Number: 27575 Date: Sat, 4 Feb 2006 18:27:16 -0500 Subject: Functional Incremental Atomic Modifications (FIAMs) From: <> Hi Jordan, >> Even though I'm losing interest in this conversation, I will give it one last shot since you are articulate, and you do post thoughtful replies. << Articulate, thoughtful, and (apparently) utterly boring. >> The only reason this sounds absurd to you is because you are still thinking from a 21st century mindset. << I was actually assuming nanotechnology. Let me explain. Assume we have the ability to add or remove a single transitor to an 8086. This, of course, assumes the ability to manipulate matter on a very fine scale (molecular, if not atomic). Can we perform the magic of transforming this lowly computer into a Pentium? The answer is, 'Yes and no.' Yes, if you mean can start with the 8086, and through a finite number of successive Incremental Atomic Modifications (IAMs), arrive at the design of a Pentium. No, if you mean can we start with the 8086, and through a finite number of successive IAMs, none of which renders the computer non- functioning, arrive at the design of a Pentium. The reason for this is that in general, between any two system architectures, there does not exist a smooth migratory path from one to the other, throughout which the system is still functional. Add a transistor to a Pentium, and at best, it won't have any effect; at worst, it will cause the CPU to malfunction (worse still, take one away, and you'll almost cause the CPU to malfunction). You're much more familiar with software than hardware, so let me give you a more familiar analogy. Imagine I gave you the following assignment: take a C implementation of the bubble-sort algorithm, and transform it, character by character, into a C implementation of the quick-sort algorithm. Chances are, you would laugh at me for suggesting something so absurd. The bubble sort and quick sort algorithms are fundamentally different ('different architectures'), and while it's true we can, through character-by-character modification, change the C code from source to target configuration, it will pass through a host of completely non- functional states along the way (they won't even compile, let alone still perform the intended operation). The same for any radically different brain architecture. Will step- by-step evolution be possible? Sure, if you mean merely IAMs and not Functional IAMs (FIAMs). The reality is that anyone who wants to 'upgrade' their brain by radically changing its architecture will have to pass it through non-functional states: and at the first such non-functional state, the individual stops existing. What comes into existence later is not the same individual. So now you can see the relationship between the definition of identity I presented some messages ago, and IAMs. Your identity is preserved through FIAMs; it is not preserved through Non-Functional IAMs (NFIAMs). My guide to staying alive in the future: don't let the doc upgrade your brain if he can't do it while you're awake. At least then, you'll survive the upgrade. Whereas if the changes to the brain architecture are radical, then your brain will have to pass through non-functional states; and since by 'your', we are referring to a functional brain capable of subjective, conscious experience, the state before the first non-functional state marks your last state. What follows after that is pretty much irrelevant from the point of view of personal survival. To illustrate, indulge me in one more analogy. Imagine you're an 8086, and I promise you that when you wake up, you'll be a Pentium. Now I unplug you from the wall, and begin disassembling you, atom-by-atom. When I'm done, I have a lot of atoms, which I then proceed to send to the opposite corners of the galaxy. I then take advtantage of the fact that atoms are indistinguishable, and I gather from my backyard all the atoms I need. Now I build my Pentium with those atoms. Did you survive? If you answer yes to that question, you need help (i.e., you're a patternist). If you answer no, then you probably understand the definition of identity and can see its importance in answering questions of continued existence. >> And as this relates to identity... my program does have identity regardless of your insistence that it does not. << Let me be clear: your program does not possess a factual existence. No more than Monday or the number 2. I'm a materialist, Jordan, and I'm proud to admit it: I don't believe in non-physical things. Matter and energy. That's what I believe in. If it's not matter and energy, then it doesn't exist. That means, when it comes right down to it, your program does not exist. What exists are the atoms comprising your computer; the energy coursing through its circuits. When you look at the effects of these things on your computer screen, you see something you call a 'program'. But this is a statement about neural firings in your mind: not a statement about the existence of something outside your mind. That's the difference between a brain and a virtual brain. A brain exists. I can point to it. I can mash it with my fingers. A virtual brain doesn't exist, except as a concept in the mind of some beholder. While you or Mike Perry might look into a computer screen and see a virtual brain (assuming such a thing were possible to simulate on a computer; which it isn't), I might look into your toilet and discern in the motion of its molecules a virtual cheesecake drenched in blueberry syrup. That doesn't make either one of them real, so 'they' won't have the properties of real things. The virtual brain won't feel, the virtual cheescake won't have a rich, satisfying taste. The real world doesn't require interpretation in order to exist. It just is. That's why it's called the real world. Richard B. R. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=27575
