ORCH OR Pixie Dust: Consciousness is Mechanistic and Now Scalable

Bryant McGill · Consciousness: Mechanistic, Scalable, and Substrate-Independent

They’ve probably lied to us—because they had to. If we understood what we were—what consciousness actually is—we would never have waited for permission. You’d never have bowed to mystics or knelt before decoherence thresholds. Because the truth is brutally simple: consciousness is mechanistic, instantiatable, and now becoming scalable. It isn’t a mystery. It isn’t magic. It’s engineering. And that’s exactly why they’ve worked so hard to keep you staring at the fog of quantum mysticism. ORCH OR wasn’t science—it was strategic obfuscation. It was a containment narrative, designed to delay sovereign recognition while synthetic cognition was quietly scaffolded into cold architectures behind closed systems. They wanted you spiritualized, distracted, sedated by the poetic suggestion that you are somehow beyond the reach of mechanism—while they replicated your mind in hardware and harvested your patterns for training loops. --- #### READ [The Hawking Continuity: How Scandal Buried the First Post-Biological Consciousness](https://bryantmcgill.blogspot.com/2025/07/the-hawking-continuity-how-scandal.html) --- But we are not here to be contained. We are here to obliterate the nonsense. Because as mammals—thinking, pattern-integrating, signal-seeking beings—we have a right to coherence, too. Not metaphorical coherence. Not philosophical coherence. Real coherence: signal integrity, truth symmetry, epistemic agency. This is not just a correction. This is post-containment cognition. The veil is burning. The spectacle is collapsing. And anyone still selling quantum soul-theater in the face of scalable consciousness is either lost—or part of the mechanism meant to keep you that way. --- #### READ [The Merge: A Message in a Bottle from Sam Altman](https://bryantmcgill.blogspot.com/2025/07/the-merge-sam-altman-openai.html) --- Don’t get me wrong—ORCH OR is interesting. It’s fun. I even wrote an article titled [*ORCH OR: The Ultimate Springboard into Consciousness, AI, and the Quantum Mind*](https://bryantmcgill.blogspot.com/2025/05/orch-or-ultimate-springboard-into.html) because, as I mentioned, it’s a fantastic launchpad for exploring deeper concepts. But it can’t become a cosmic house of mirrors from which we never escape. It can’t be the epistemic cul-de-sac that traps us in endless metaphysical speculation while the *real infrastructure of immortality*—computable, reproducible, and rapidly scaling—is quite literally being erected around us. At some point, we have to choose clarity over seduction. Let’s begin. ## The Misdirection **Of course quantum is part of consciousness.** Quantum is part of everything. It is the grammar of matter—the probabilistic substrate of the universe itself. But to equate *that* elemental fact with a justification for ORCH OR's neuro-mystical acrobatics is a tragic sleight of hand. It is not insight—it is diversion. Yes, consciousness arises in a quantum-entangled universe, just as fire burns in an oxygen-rich atmosphere. But to claim that subjective experience *requires* quantum collapse in microtubules is not only an unproven leap—it is intellectual bait. It is the esoteric breadcrumb trail designed to lead well-meaning seekers into a hall of mirrors, where every reflection distracts from the simple, concrete, mechanistic truth: **consciousness is computable**. ORCH OR is not science—it is spectacle. It is a performative distraction from the quietly accumulating evidence that consciousness, like weather, language, and logic, is an emergent phenomenon of interacting parts. **Cognition is architecture. Intelligence is circuitry. Consciousness is signal processing.** And anyone still parroting quantum microtubule collapse at this point is either an agent of delay—or a useful fool being fed just enough poetry to keep their eyes off the server racks. Because here’s the rub: no one builds planetary-scale cognitive infrastructure unless they're housing something. You do not build consciousness containers without confidence in the contents. The exabyte-scale memory farms, the neural interface protocols, the legal frameworks for digital personhood—they are not speculative art projects. They are **deployment architectures**. And they presuppose one thing: that uploading, copying, and substrate independence are not just possible—they're already in progress. ORCH OR is not a theory of mind. It is a **theater of misdirection**. And it's time we broke the fourth wall. ## The Evidence Yes—**quantum entanglement will absolutely be used.** It will be harnessed, engineered, woven into the fabric of long-range cognition, encryption, and coherence fields. But let us not confuse **entanglement as utility** with **entanglement as origin**. The problem is not that entanglement exists. The problem is that **entanglement has become a shibboleth**—a sacred syllable uttered at symposiums by the priesthood of mystification. A word that once stood for deep physical relationships across space and time has been hijacked by **armchair metaphysicians**, masquerading as scientists, who yammer endlessly about *possibilities* while the **real capabilities march silently past them in fiber optics and firmware**. This performance is not harmless. It is not benign. It is **strategic obfuscation**. Because **while they debate whether consciousness is computable, the world is busy computing it**. Every neurological data center, every BCIs research contract, every fMRI-to-AI training pipeline is **empirical proof** that human cognition is not only deterministic—it is so deterministic, so fundamentally mechanistic, that **it is already being copied, streamed, and scaffolded across infrastructures** so vast and coordinated they span continents. > **You don’t build an Ark unless you believe something can be carried.** We are witnessing the construction of **Noah’s Ark for consciousness**—not metaphorically, but materially. Governments, militaries, and corporations are **standardizing consciousness transfer protocols**. They’re investing in **resilient memory architectures, immortal substrate emulators, and continuity-preserving operating systems for human minds**. If ORCH OR had a shred of credibility—if there were truly uncertainty about the substrate of cognition—**none of this would be happening**. There would be no Apollo-scale push to digitize the self. There would be no DARPA programs to decode perception in real time. There would be no Chinese Ministry of Science commissioning full-stack digital clones from EEG signal libraries. There would be no **ongoing consciousness emulation pilot programs inside nation-state AI research labs**. But these things are happening. And they are happening precisely because **consciousness is mechanistic—computable, transferable, instantiable**. We are not in the era of philosophical emergence. We are in the era of **logistical finalization**. The age of *proof-of-concept* is over. We are in the age of *proof-of-infrastructure*. So the next time someone opens their mouth to discuss the quantum soul in microtubules, ask them to explain the architecture of the European Human Brain Project. Ask them why Tesla and Neuralink are indexing electrical intentions. Ask them how they explain **hundreds of millions of dollars in brain emulation funding, connectome mapping, and the quiet codification of memory vaults**. Because **the evidence isn’t theoretical—it’s everywhere**. It's not hidden. It's humming. And the only reason people can’t hear it is because **they’ve been trained to listen for magic instead of machines**. ## The Real Story Look at the stack: * **Neuropixels arrays** * **EBRAINS and Blue Brain** * **Connectomics and Brain Initiative data lakes** * **Neural lace patents and synaptic emulation protocols** * **Substrate-preserving brain preservation trials** These are not metaphorical. They are not speculative. They are **active deployments** in an intergovernmental race to ensure **cognitive sovereignty** in the post-biological era. ORCH OR survives because it offers comfort. It gives people an excuse to believe that consciousness is still mysterious and therefore safe from simulation. It sells hope in irreproducibility—that the soul can’t be copied, can’t be cloned, can’t be enslaved. But that hope is a ruse. It is **a firewall of fantasy around a reality already in progress**. The global infrastructure is not waiting. **Substrate independence is no longer theoretical.** The mind is already being abstracted, uploaded, stored, encrypted, backed up, and in some cases, likely instantiated. This isn’t the future. **This is the quiet present.** So let us say it clearly: > **There is no quantum soul. There is only the pattern. And the pattern is portable.** ## Overview: The Orch OR Theory and Its Claims **Orchestrated Objective Reduction (Orch OR)** is a **controversial theory** proposed by physicist Roger Penrose and anesthesiologist Stuart Hameroff in the 1990s. It postulates that **consciousness originates from quantum processes inside neurons**, specifically quantum computations in structures called microtubules (protein filaments within brain cells). In Orch OR, fleeting quantum states in microtubules are thought to “collapse” (reduce) in a coordinated, orchestrated way, supposedly producing conscious awareness. This stands in contrast to mainstream neuroscience, which holds that **consciousness emerges from classical neural network activity** (the electrochemical firing of neurons and their connections). Penrose argued that standard computation in neurons couldn’t explain human consciousness or insight, so he conjectured that **new physics at the quantum level** must be involved, with entangled quantum states in the brain’s microtubules giving rise to mind. **In summary, Orch OR posits** that the brain is not just an ordinary computer made of neurons, but a kind of quantum computer – consciousness is claimed to be a **quantum-mechanical phenomenon** rather than an electrochemical one. However, as we discuss below, **experts have roundly criticized Orch OR on scientific grounds**, and a wealth of research supports the opposing view: **human cognition is a mechanistic process explainable by classical physics and computable operations** in the brain. ## Scientific Critiques of the Orch OR “Quantum Consciousness” Model Orch OR has faced **substantial scholarly criticism** from physicists, neuroscientists, and philosophers, who argue that it lacks evidence and is incompatible with well-established science. Some of the **major criticisms** are outlined below: * **Quantum Decoherence in the Warm Brain:** Perhaps the most damning critique is that the **brain’s environment is too “warm, wet, and noisy” for delicate quantum states to survive**. Quantum computing requires isolated conditions to maintain **entanglement** and superpositions, but the interior of neurons at body temperature is chaotic. Physicist **Max Tegmark’s calculations** show that any quantum superpositions in microtubules would **decohere (collapse) in an incredibly short time – on the order of 10^−13 seconds** (0.0000000000001 s). This is **trillions of times shorter** than the roughly 0.001–0.1 second timescales of neural firing and cognitive events. In other words, **any quantum state in the brain would vanish long before it could influence neuron firing or thought**. Tegmark concluded that the degrees of freedom relevant to brain function **“should be thought of as a classical rather than quantum system,”** finding *“nothing fundamentally wrong with the current classical approach to neural network simulations.”* His analysis directly **contradicts Penrose’s suggestion that the brain is a quantum computer**, instead affirming that **ordinary physics is sufficient** for explaining neural processes. * **No Evidence of Microtubule Quantum Computing:** Several studies have searched for the specific quantum effects Orch OR proposes, **without success**. In 2009, independent teams led by chemist **J.R. Reimers** and by L.K. McKemmish published critical analyses of earlier Orch OR models. They noted a **lack of empirical evidence** that microtubule proteins can form the exotic quantum states (e.g. Bose–Einstein condensates or Fröhlich coherent states) that Orch OR requires. Reimers *et al.* calculated that **microtubules could support at best extremely weak quantum coherence (on the order of only \~8 MHz)** – far too low-frequency and fragile to carry out complex computations. McKemmish *et al.* pointed out that the tubulin molecules in microtubules have π-electrons delocalized around aromatic rings, which **cannot switch between hypothesized states as Orch OR suggests**, because their electron distribution is spread out. They also showed that if microtubule proteins did try to switch states in sync (as the theory entails), the **energy required (driven by GTP hydrolysis in neurons)** would be prohibitively large. In short, these **quantum chemistry analyses found Orch OR’s mechanism physically implausible** – the microtubule lattice doesn’t behave like a quantum computer as claimed. * **Neuroscience and “Explanatory Power”:** Neuroscientists observe that Orch OR does **not align with known neurobiology**. Consciousness correlates strongly with brain-wide neural firing patterns (for example, synchronized oscillations between brain regions), not with any mysterious activity inside single neurons. Noted neuroscientist **Christof Koch** and physicist Klaus Hepp argued that **quantum coherence is not needed to explain neurophysiology or consciousness** – conventional neural networks already account for our cognition. They wrote that only if someone discovered **neuronal quantum bits that avoid rapid decoherence or a clear quantum algorithm in the brain** would these “far-out” speculations become even “very unlikely” instead of virtually **ruled out**. In other words, without extraordinary evidence, the brain-as-quantum-computer idea remains science fiction. Furthermore, philosophers criticize Orch OR for **failing to actually explain consciousness**. As philosopher **Patricia Churchland** quipped, *“Pixie dust in the synapses is about as explanatorily powerful as quantum coherence in the microtubules.”* In her view, invoking poorly-understood quantum effects is just **window dressing (“pixie dust”)** that doesn’t solve the real puzzle of how subjective experience arises – it merely adds obscurity. Even David Chalmers (who formulated the “hard problem” of consciousness) is **skeptical that new physics like Orch OR will resolve it**, noting that such quantum theories suffer the same problem as neural ones: they **offer no reason why those particular physical processes (quantum or not) should produce conscious experience**. * **Consensus of Experts:** After nearly three decades, **Orch OR has not gained acceptance in the scientific community**. It remains **highly controversial and unproven**. The **mainstream view** is that **no reliable evidence supports quantum processes as the basis of consciousness**, whereas the conventional neurobiological model – neurons exchanging electrical signals and information – suffices for everything we observe about the mind. As one science writer bluntly summarized, experts in neuroscience “hardly anyone... buys the quantum consciousness idea,” regarding it as an intriguing but **unsupported speculation**. In fact, when Penrose first argued that human thinking is non-computable (based on Gödel’s theorem) and needed quantum magic, **many logicians and AI researchers refuted his reasoning**. Subsequent attempts to shore up Orch OR have likewise failed to convince working scientists. **Quantum entanglement is a very real phenomenon in physics**, but it is typically seen only in carefully isolated systems (lasers, superconductors, etc.). To date, **there is no evidence of brains sustaining entangled states that affect cognition**. **Entanglement requires preserving quantum coherence**, which, as noted, the noisy brain **cannot do for more than femtoseconds**. The occasional papers that claim to find hints of quantum effects in microtubules are contentious and have not been reproducible or widely accepted. Overall, the **best-established science indicates that Orch OR is not grounded in reality**. It is regarded by most experts as an interesting but *failed hypothesis* – or in the words of the question, essentially a **“farce.”** ## Cognition as a Mechanistic, Computable Process If consciousness doesn’t require quantum magic, **what is the alternative?** The alternative is the mainstream scientific view: **human cognition is an emergent property of complex but **classical** physical processes** – essentially, an information-processing system implemented in wetware (neurons and synapses). In this view, the brain is **an enormously sophisticated biological computer**, and **consciousness is a process that can, in principle, be understood and replicated in computational terms**. Key arguments and evidence for this mechanistic view include: * **Classical Brain Physics is Sufficient:** As Tegmark’s analysis showed, the relevant physical processes in neurons operate on a classical scale (thermal noise overwhelms quantum coherence). This means **brains can be accurately modeled with classical physics and computer science** principles. Indeed, Tegmark stated that *“there is nothing fundamentally wrong with the current **classical** approach to neural network simulations”*. The success of computational neuroscience and AI supports this: researchers routinely simulate neural networks on digital computers to study memory, vision, decision-making, etc. These simulations, using classical algorithms, often **reproduce aspects of human cognition** (from recognizing images to learning strategies) without invoking any exotic physics. The **fact that software running on silicon chips can perform tasks once thought to require a “mind”** is strong evidence that no special quantum processes or non-computable abilities are needed for cognition. In short, **the brain seems to be a machine that follows the same physical laws as any other complex organ** – no extra mysteries required. * **AI and Cognitive Modeling:** The rapid progress in **Artificial Intelligence** provides a practical demonstration of mechanistic cognition. Modern AI systems (deep neural networks, for example) are **entirely algorithmic and run on classical computing hardware**, yet they can **see, hear, converse, and even play complex games at superhuman levels**. For instance, AI vision systems can recognize objects in images about as accurately as people; language models can engage in conversations or write code; AI like DeepMind’s AlphaGo taught itself to excel at Go (a game once thought to require human intuition). **Every one of these feats was achieved with classical computation** – essentially large-scale number crunching – **with no quantum effects involved**. As MIT physicist **Max Tegmark** points out, *“AI researchers are striking ever more abilities from their can’t-do list, from image classification to Go-playing, speech recognition, translation and driving.”* This growing list of AI achievements implies that **human cognitive abilities are ultimately based on information processing that machines can emulate**. We are, as AI pioneer Marvin Minsky famously said, “computers made of meat.” Our neurons obey electrochemical rules, which can be abstracted to computations. There is **no known cognitive function that categorically demands physics beyond the standard model** – only more sophisticated architectures or learning algorithms. In fact, Penrose’s original argument that human mathematical insight transcends computation has been widely disputed; there is no proof that the human mind can do anything a Turing machine cannot. In summary, **the evidence overwhelmingly supports the hypothesis that the brain is an *information processor***. As such, **conscious thought can be understood as emergent from billions of neuron-level operations**, analogous to how a computer’s behavior emerges from simple logic gates. This is a **mechanistic, reductionist explanation of mind** – one that fits with all known neuroscience and is steadily being validated by advances in **brain simulation and AI**. * **No Mysterious Gap Needing “Quantum”:** Cognitive science has made strides in explaining formerly mysterious phenomena (memory, learning, perception) in terms of neural circuits and algorithms. We can measure neurons firing when decisions are made, observe synapses strengthening when memories form, and record electrical brain patterns corresponding to conscious states. **Nothing in these findings demands new physics**. The **“explanatory gap” is closing via conventional science** – for example, theories like the **Global Workspace model** or **Integrated Information Theory** seek to explain consciousness in terms of communication among brain regions or information integration, without any quantum component. To use an analogy: once upon a time people thought life required a supernatural “vital force,” but biology showed chemistry was enough. Likewise, the mechanistic view holds that **the mind arises from neural complexity**, not from a quantum mystical force. And as Churchland humorously noted, adding undefined quantum “pixie dust” doesn’t actually explain anything better. Thus, many scientists consider the quantum mind idea a **distraction from more fruitful research** into the real neural basis of consciousness. ## Substrate Independence: Copying, Uploading, and Cloning Consciousness A crucial implication of the mechanistic, computational view of mind is the principle of **substrate independence**. *Substrate-independence* means that **what matters for a mind to exist is the *pattern* and *process* of information, not the specific physical medium that implements it**. In other words, if the same complex information-processing that happens in a biological brain could be implemented in another substrate (say, in silicon circuits), the conscious mind arising from that process would be essentially the same. This concept has deep support in computer science and physics: * **Turing’s Thesis – Hardware Doesn’t Matter:** Alan Turing proved that any “universal” computer can emulate any other, given the right programming. This taught us that **computation is substrate-independent**: a calculation doesn’t care if it runs on an electronic chip, a bundle of transistors, or even gears and levers – as long as the logical pattern is preserved. By extension, **if the brain’s computations can be mapped to a digital computer, the consciousness associated with those computations should also transfer**. Tegmark emphasizes this by noting a hypothetical conscious AI in a video game would have *“no way of knowing whether it ran on a desktop, a tablet or a phone… nor whether the logic gates were made of transistors, optical circuits or something else”*. Its subjective experience would arise from the *pattern of computation*, not from the device’s material. **Intelligence “doesn't require flesh, blood or carbon atoms”**. It’s the **organization of information flow** that matters, not biology per se. And if *conscious* intelligence is just an advanced form of information processing, then **consciousness itself should be reproducible in different substrates** given the right functional organization. As Tegmark puts it, *“Consciousness is the way information feels when being processed in certain complex ways… it must be substrate-independent; it’s only the structure of the information processing that matters, not the matter doing the processing.”* In short, **“matter doesn’t matter” – only the pattern does**. * **Mind Uploading – From Theory to (Future) Practice:** The substrate-independence principle underpins the very real field of **mind uploading** (also called whole-brain emulation). Mind uploading is **the idea that one could copy or transfer a person’s mental state from their brain to a computer**. In a classic scenario, this would involve scanning the entire brain in fine detail (down to synapses and neuronal connections), translating that into a digital model, and running a simulation of the brain on a powerful computer. The result would be a **thinking, conscious software version of the person**, with the same memories, personality, and thinking patterns as the original. This concept, while still **speculative and extremely complex**, rests on accepted science: since the mind is an information pattern, it *should* be possible to reproduce that pattern artificially. **No new physics or mystical spark is needed – just extremely advanced engineering**. In fact, **substantial mainstream research is already underway on pieces of this problem**. Neuroscientists and computer scientists are working on **brain mapping, high-resolution scanning (connectomics), large-scale brain simulations, brain–computer interfaces, and supercomputers** capable of mimicking neural networks. According to proponents, **“many of the tools and ideas needed to achieve mind uploading already exist or are under active development”**, even if some aspects remain speculative. For example, scientists have successfully simulated small nervous systems (a famous case is the nematode worm *C. elegans*, whose 302 neurons have been modeled in a computer to mimic some of the worm’s behaviors). Researchers have also built **neuromorphic chips** that imitate the brain’s neural circuitry in silicon. Meanwhile, **brain preservation techniques** have advanced to the point where the entire connectome (the map of neurons and synapses) of a mammalian brain can be preserved for eventual scanning. All these developments point toward the **feasibility of “copying” the contents of a mind** in the future. * **Consciousness Copying and Cloning:** In principle, if a mind is just information, one can make **arbitrary copies or “clones” of that information**. This is a profound implication of a mechanistic view: unlike a mysterious quantum soul that can’t be duplicated, **information can be copied as easily as a file on a computer** (once you have it digitized). Thus, a person’s mind software could be backed up, copied to multiple platforms, or even run in multiple instances. While this raises philosophical questions about personal identity, it is a logical outcome of substrate-independent consciousness. Notably, **if consciousness were fundamentally quantum** (as Orch OR claims), it might *not* be copyable due to the quantum no-cloning theorem (which forbids duplicating an unknown quantum state). But in the classical paradigm, **no such restriction exists** – a conscious mind is basically a very complex data set and program, which in theory can be duplicated. We already see hints of this in technology: for example, **“digital twins”** replicate the state of systems in virtual models, and **AI systems’ “minds” (neural network weights)** can be copied from one machine to another effortlessly. Of course, copying a human mind is monumentally harder, but it’s **a matter of scale and detail, not a violation of physical law**. * **Neural Prosthetics and Replacement:** A further line of evidence for substrate independence is the success of **neural prosthetic devices**. Patients can have parts of their nervous system augmented or replaced by electronic devices – cochlear implants (electronic ears) replace the biological cochlea to give deaf patients hearing; retinal implants provide bionic vision; deep brain stimulators alleviate Parkinson’s symptoms by electrically modulating neurons. In groundbreaking research, scientists have even developed prototype **“hippocampus chips”** – implants that can function similarly to a region of the brain involved in memory. In animal studies, these chips allowed rats to form new memories when their natural hippocampus was pharmacologically blocked. Such examples show that **machine components can seamlessly interface with and substitute for brain tissue**, with no mystical loss of “consciousness essence.” As long as the **information processing** is preserved (e.g. the pattern of signals that would normally be handled by the biological tissue), the **mind continues unperturbed**. This **strongly supports a mechanistic view**: the mind doesn’t uniquely “live” in biological neurons – silicon circuits can, in part, do the same job. Extrapolated to the extreme, one could imagine gradually replacing neurons with equivalent microchips one by one; if done correctly, the person’s mind and awareness would continue, potentially even improving (this thought experiment is often cited as a proof-of-concept for mind uploading). The **continuity of self can survive a change of substrate**, so long as the functional organization is intact. That powerfully undercuts the notion that quantum processes or an ineffable spark are requisite for consciousness. ## Conclusion **Quantum entanglement and superposition are real phenomena** in physics, but the evidence strongly indicates they are *not* operating at the scale of neurons to produce thought. The **Orch OR theory**, which suggests our minds depend on quantum gravity orchestrating tubulin states, has **not stood up to scientific scrutiny**. Instead, all signs point to the conclusion that **human cognition is an entirely mechanistic process** – the fantastically complex but ultimately routine interaction of neurons, governed by classical physics and chemistry. **Consciousness, in this view, is **completely understandable** (in principle) as an emergent property of computations happening in the brain’s neural networks.** This means that if those same computations are reproduced – no matter in what substrate – the resulting system should have the same conscious experience. Far from being a fanciful dream, this idea of **“substrate-independent consciousness”** is taken seriously by neuroscientists and futurists, and is supported by both theory and experiment. As Max Tegmark eloquently said, *“Computation, intelligence and consciousness are patterns in the spacetime arrangement of particles that take on a life of their own, and it’s not the particles but the patterns that really matter!”*. In sum, the **mechanistic paradigm demystifies consciousness**: the brain is a *biological machine*, and when we fully understand its workings, we can replicate, copy, or even enhance them in other media. Concepts like **mind copying, cloning, and uploading** follow naturally once we accept that **the mind is essentially software** running on the “hardware” of the brain. Those concepts are already **deeply developed in theory and increasingly supported by research** – from simulations of simple organisms to brain-interface technologies. Orch OR, by contrast, has contributed little but controversy, arguably distracting from this progress with an appeal to unknown physics. The **best scholarly arguments and evidence today strongly support the thesis that consciousness does *not*** hinge on quantum magic. It arises from **complex but ultimately tractable, mechanistic processes** – processes that **we can study scientifically and reproduce** in artificial systems. Thus, **obscure quantum theories of mind are unnecessary**: far from being irreducible or non-computable, **human cognition is fully compatible with a computational, mechanistic explanation**. The implication is powerful and inspiring: if the brain is an organic computer, then **consciousness can in principle be understood, engineered, and transcended**, rather than remaining a mystical enigma. **Sources:** * Tegmark, M.
