Explain to me why downloading&uploading your mind into a computer isn't possible yet
is it a scaling issue? would you need a million datacenters for one brain?
a lack of technology issue?
what is it?
what prevents us from scanning a bunch of synapses and map them onto artificial ones?

Because is just an deus ex machina plot device like time travel, resurrection, teleportation, typical of crappy literature.
You believe your mind is some collection of concepts you can write on a sheet of paper.
But is 10E27 atoms in an uncomputable complex combination that can't be just copied.
>>
>>
The brain is a complex biological system which involves a lot a chemical reactions which are basically physics stuff, so, to replicate just one single brain you would probably need an entire datacenter if not something bigger than that. “Mapping the synapses” is just like drawing a brain on paper, it is useless if you don’t replicate all the chemical-physical processes involved in them, but to do so you need a huge amount of power, very very huge for just one brain.

Our minds are based on carbon (neurons). Computers are made of silicon (chips).
Carbon can carry a lot more information. You can pack it more than silicon because it's smaller, and it carries more electrons (so transmits more information). You would need a silicon computer to equal the processing power of the brain (which would need to be about the size of the moon), or a carbon-based computer.

In principle it would be possible to create an exact copy ... in all practicality, how the hell would you even accurately measure the reaction a single neuron would show, also considering its plasticity? You would never get it quite right. Now multiply that "not quite right" by the total number of neurons you need to simulate. The result would be wildly different from what you try to copy!

It's delineated to some degree, sure. You will never find a rigorous definition of any of these processes in any serious publication about information processing in the brain, because these ideas need to be continuously modified based on new discoveries in the future. Researchers don't want to invest their careers in ideas that might be completely invalidated by new discoveries in the future.

Computation is a process that evaluates a computable function for some input. A function is computable only if it can be evaluated by a finite algorithm on a Turing machine. This is the accepted definition outside of your cult's context.

To clarify (for retards like you) "can be evaluated" means the algorithm yields the value in a finite number of steps.

>>16918526
Psychiatrist here. You are grossly overestimating our current understanding of how the brain functions. You are asking why we can't make a digital model of a physical, chemical structure. We've learned an incredible amount about how the brain functions but we're still pretty clueless when it comes to much of how it works, why it works, what influences how it works, and so on.
As one of many examples, the presence or lack of certain bacteria in your intestines can affect your mood due to the various chemicals they secrete. How would you replicate this digitally?
Serotonin has been thought for many years to be a causal factor in depression, such that there is an entire class of drugs devoted to modulating serotonin levels in the brain. Recent research has called this into question and there is regular debate not only on their effectiveness but even on their mechanism of action. We still don't understand exactly how these drugs are effecting the brain, nor what exactly the various neurotransmitters do. We know a lot about these subjects, and we're constantly learning more, but enough to replicate a brain? Not even close.
Assuming you did find some way to digitally map the physical structure of the brain, something that's already an impossibility, you'd then be left with the much more difficult task of digitally mapping the chemical structure of the brain, something that is far less understood. Your brain is constantly adding or removing various chemicals. Every sensation or emotion you feel has a chemical basis in the brain. How would you replicate this digitally?

Lol, under your retarded definition, a computer running an infinite loop is not computing anything. This is why retarded schizos shouldn't try to define things.

That will terminate eventually, retarded jeet. Probably as soon as you die from your intestinal parasites and your mother unplugs your computer. Now, if you put a Turing machine in an infinite loop, then indeed, you are not computing anything. This is only controversial in your mentally ill brown mind.

Your mentally ill retardation simply doesn't matter. An infinite loop doesn't compute anything in theory and doesn't even exist in practice. You can perform computations inside a loop with no terminating condition but that doesn't help the computationalist case in any way.

While(1)x++ computes the next value of x, though, you just don't want to admit how infinite loops work and just found a way to reword infinite loop as no termination condition loop.

That's not even the point. Mentally ill retards are simply incapable of basic reading comprehension. An infinite loop is a finite algorithm is finite algorithm but it doesn't evaluate to anything, so it's not computing a computable function.

Continuous fluid dynamics is irrelevant in reality because fluids are made of atoms. Thus, there is an inherent discreteness to them. This means that at some level, the discrete "approximation" becomes exact.

If I have an actual computer running an algorithm that computes something, I can abstract the algorithm from the hardware. It doesn't have to be a general-purpose computer that runs arbitrary software. Even if the instructions are built into the hardware architecture, they can be reasoned about as steps in an algorithm that I can run on different hardware.
I'm still waiting for the Computationalism cult to tell me what algorithm the brain running and what computable function it's supposed to be computing. If the standard definition of computation (the one used by computer scientists and computing hardware engineers) doesn't suit you, feel free to rigorously specify your cult's favored alternative. :^)
None of that is going to happen, obviously. In the end of the day, such "discussions" boil down to mouth-breathing retards erroneously thinking that if you make a computational model of some brain dynamics, on whatever crude level of abstraction is considered SOTA in the Current Year, it magically turns the brain into a computer that computes their model. Nevermind conflating the map with the territory; these people are too fucking dumb to at least do it in a way that isn't blatantly circular. Pic related.

Your mind isn't flat all the time like a computer's mind is. Your mind warps and wobbles as needed to take on incoming data. Simple data = stays euclidean. Complex data = goes hyperbolic.
If you want to put people's minds in a computer, you'd need to make a computer chip that can alter its geometry like the brain does.

We don't even know what the self is. Of course, what we call self is a certain neuron system running, and that probably gets updated and replaced as we live, we may never be the same person as we age, for all we know a guy with dementia may already be on spectator mode after certain brain deterioration and his executive functions may continue to be performed by a secondary consciousness, so to us he just seems to be retarded but he's already dead by that point.
For all we know, the self could be a unique reaction, even if you were to copy that and emulate it on a digital system the authentic reaction would just die out. Is a flame the instant flash that reaches our eyes or the continuum of combustion for as long as it lasts?

if it were really this simple animal intelligence would be trivial to emulate
we still can't emulate worms, especially because we still don't know how learning/memory actually works.
the connectome is insufficient, we've known this for decades now.
>>16918840
we actually have a lot of evidence now it's at the very least not a Markov process. LLM architecture, as a unidirectional series of fully connected bipartite graphs, is pretty much the highest scale and complexity of Markov process you can create with finite materials and energy (nearing theoretical maxima for all practical purposes). and it's become clear (at least to anyone not financially dependent on LLMs being AGI) that they don't emulate intelligence.
they don't and can't "think."
the action potential threshold/connectome model that "artificial neural nets" are based on is extremely simplistic and has not really been updated since the 1950s except by modifying backpropagation formulas. modern implementations just use orders of magnitude larger scale.
there are parts of brains that MAY work this way - namely, for example, the motor cortex - but it's clear at this point that "thinking" requires more than an infinitely scaled motor cortex.
but all the money's going to LLMs so when that bubble pops we'll be stuck in another AI winter, probably.

Prompt:
"Identify a few archetypes of posters in this thread and evaluate the validity of arguments that they are making."
Response:
1. The Skeptical Scientist / Realist
Examples:
Post #16918888 (Psychiatrist)
Post #16919981 (AI/Neuroscience Critic)
Post #16918727 (Physics/Chemistry Focus)
Arguments:
Highlights the brain’s biological complexity (chemical signaling, plasticity, gut-brain axis).
Notes we lack even basic understanding of neurotransmitter roles or memory mechanisms.
Points out that mapping synapses ≠ replicating function; analog biological systems can’t be perfectly digitized.
Validity:
Highly valid. These posters ground their arguments in current scientific limitations. Neuroscience hasn’t cracked the “hard problem of consciousness” or even fully mapped a worm’s brain. Emulating a human brain requires solving unknowns in neurochemistry, quantum biology, and emergent properties—far beyond today’s tech.
2. The Computationalist / Turing Advocate
Examples:
Post #16918869 (Defines computation via Turing machines)
Post #16918913 (Brains compute sensorymotor output)
Post #16919053 (Cites NIST on “brain-inspired computing”)
Arguments:
Claims brains compute because they process inputs outputs via algorithms.
Insists computation is rigorously defined (Turing machines, finite algorithms).
Suggests digital systems can approximate biological processes.
Validity:
Partially valid, but oversimplified.
Strength: Computation can be defined rigorously (Turing completeness).
Weakness: Equating brain function with “computing a function” ignores context: brains are embodied, analog, and dynamic. A Turing machine doesn’t account for emotion, embodiment, or quantum effects.
Flaw: “Brain-inspired computing” (e.g., neural nets) ≠ brain emulation. LLMs don’t “think”—they pattern-match.
(Cont.)
>>
>>16918890
>>16920137
3. The Anti-Computationalist / Dualist
Examples:
Post #16918541 (“Mind is not computation”)
Post #16918587 (“10E27 atoms = uncomputable”)
Post #16919693 (“Mind = soul, immaterial”)
Arguments:
Mind/consciousness is non-physical or emergent in ways algorithms can’t capture.
Brains involve quantum effects or “uncomputable” complexity.
Rejects reductionism: mapping synapses is like “drawing a brain on paper.”
Validity:
Philosophically coherent, scientifically unproven.
Strength: Correctly notes that consciousness isn’t reducible to current computational models.
Weakness: “Quantum brain” theories (e.g., Penrose-Hameroff) lack evidence. “Soul” arguments are metaphysical, not falsifiable.
Risk: Dismissing computation entirely ignores progress in AI/neuroscience (e.g., brain-computer interfaces).
4. The Troll / Provocateur
Examples:
Post #16918538 (“Convert brain to 0s and 1s”)
Post #16918763 (“It would be extremely painful”)
Post #16918867 (“Acquire a soul gem”)
Arguments:
Absurd or sarcastic takes (e.g., “soul gems,” “painful upload”).
Mocks both sides (“cult” rhetoric, “moldovan schizo” insults).
Validity:
Not valid arguments. Purely disruptive. Adds noise but no substance.
5. The Theological Moralist
Examples:
Post #16918781 (“God gave us bodies”)
Post #16918796–#16918808 (Debate on “God’s order”)
Arguments:
Mind uploading violates divine design.
Free will ≠ permission to defy “God’s will.”
Validity:
Not scientifically valid. Faith-based objections don’t address technical feasibility.
>>
>>16918890
>>16920137
>>16920138
Key Takeaway
The most credible arguments come from Skeptical Scientists and Anti-Computationalists, who emphasize:
Biological complexity (chemical, quantum, emergent).
Current technological gaps (no brain map, no theory of consciousness).
Philosophical limits (can a copy be you?).
Computationalists offer useful frameworks but overextend them. Trolls and theologians derail the discussion.
Bottom line: Mind uploading isn’t possible today due to scientific ignorance, not just engineering limits. We don’t even understand how memory or consciousness work—let alone replicate them.

Probably just a network state of awareness, possibly with some predictive capability of its own but here the question is how much that is even intrinsic to the awareness component and how much is outsourced by it. Now a dementia patient likely still has that unless completely unresponsive already (at that stage likely properly "braindead") but the rest of the brain feeds mostly bullshit into that. I rather see that a possible high fidelity copy of a brain could sure show similar reactions to the original, it would be a properly faithful zombie in a sense. It could even develop its own awareness, but in no sense would that be continuity for the original.

It all comes down to application, and that's for those who have the strength of character to undertake it properly in the future.
