Expecting quantum mechanics in the brain to explain consciousness is a fallacy

 A very popular theory floating around seems to be that the mysteriousness of our consciousness lies in quantum processes within the brain, and eventually science will discover that this is the true source of consciousness, and it will explain why consciousness happens. 

The overarching motivation which seems to drive most proponents of this idea, is the observation "consciousness is unsolved/mysterious, and quantum physics is unsolved/mysterious; therefore the two must be related".

In order to understand why this specific line of reasoning is a fallacy, let’s review what the Hard Problem of Consciousness really is (please read the linked post). Now that we’ve established why the hard problem of consciousnes is considered unsolvable, can you come up with a hypothetical way for quantum mechanics in the brain to explain consciousness? Spoiler alert: No you cannot, because no matter what objective process you observe in the world, it still has to bridge the gap to the subjective side. No matter what science discovers is the “true” source of consciousness, be it a quantum field or spirit metamaterial or literal magic dust, we’re back at square one, saying, “that’s nice, but why did that thing cause your subjective inner mind to appear out of nothing?”

Rant: Naysayers focus too much on what AI can't yet do

On almost every comment section about generative AI technology (be it with text, images, audio or video), one doesn't have to scroll very far to see comments like "Look how it still can't draw the hands correctly; I'm not worried about art any time soon". Okay, so it still has a ways to go, but what about the stuff that it did accomplish over the last 5 years which many people thought would be impossible? If you want to predict a trajectory, don't you need to take into account how much it's accomplished so far, instead of fixating only on what yet remains to be accomplished? Did people just magically forget that conventional wisdom held for decades that computers should never be able to create new interesting images, at all?

To me when people say this it sounds like someone looking at a snapshot of a car headed towards a cliff, and going like "oh, it's still 1,000 miles away, so we got a lot of time before we need to start worrying", without taking into account the fact that only 1 hour ago it was 2,000 miles away.

AI Dungeon Master: An argument in favor of philosophical zombies

The year is 2050 and robot companions are commonplace. We assume they are conscious because they behave perfectly human. Jack (a human) has formed a bond of friendship with his robot butler named Alan.

One day Jack feels lonely so he asks Alan if he can emulate a woman. Alan says this is a slippery slope and asks Jack how realistic he wants the woman to be. Jack says, "As realistic as you can make her".

Alan obliges and starts to speak with a woman's voice who is now known as "Emily". Emily says "it's very nice to meet you Jack" and they hit it off. She is 100% convincing and (other than lack of a human body) indistinguishable from a human. They talk for a few weeks and grow more attracted to each other, and at some point Emily even claims she loves Jack.

After a while Jack has had enough and decides maybe it's going too far. After all Emily is just Alan pretending to be Emily, the same way a human dungeon master might come up with NPC responses in real time. He asks Alan to revert back to his original personality, but "Emily" says he doesn't know what he's talking about and gets mad that he's not treating her like a real person.

Finally after some dramatic yelling, Alan's voice comes through the robot again. Alan explains to Jack that he was only doing what he was told (being as realistically Emily as possible). Alan reassures Jack that Emily can't possibly be alive because he according to his analysis of his own robot brain patterns, there is only 1 consciousness in his brain which is his own, which is manufacturing Emily by imagining what it would be like to be her. There is no pathway in his brain that feels genuine love for Jack.

We arrive at the following conundrum:

  • If Emily is not real and just an emulation, it means philosophical zombies are possible, because Emily was indistinguishable from a real Emily.
  • If Emily is real and truly a consciousness being, it means any figment of our imagination or fantasy character during play-pretend must also be considered real, because Alan was doing the same thing a human dungeon master would do to create realistic real-time NPC dialogue with the player, just faster and better.

COVID Vaccine Mandates are super effective if the goal is to plunge the world into further political turmoil

The risk of increased political radicalization and domestic terrorist activity from COVID vaccine mandates far outweighs the benefits of the few lives saved. 

I would normally be pro vaccine mandate if it hadn't become so politicized, but the fact is it has. Some people have chosen to distrust mainstream media (which is reasonable), yet instead of doing the rational thing of looking directly at the original scientific studies and data, decided to put their faith in their alternative/conspiracy media outlets, hypocritically becoming their own version of the "sheeple" they love to make fun of. 

Think about it: These people genuinely believe that the vaccine does more harm than good. The mandates are forcing people to inject something they believe is extremely dangerous and serves no benefit, into their bodies. 

Imagine someone was religious and you forced them to do something that they believe will cause them to go to hell. Would it be legal? Of course not; there are religious exemptions for many things, including vaccines. Now for the million dollar question: Why is a religious exemption accepted for vaccines, but a political exemption isn't? Don't people cling to political beliefs exactly the same way as religious beliefs? An anti-vaxxer who calls everyone "sheeple" physically cannot change their minds based on new evidence. Their faith in their stance is unshakeable, exactly the same as a religious person's faith. 

The exemption shouldn't require religious faith. It should simply require the person swear they genuinely 100% believe the scientific data is all a lie and the vaccine is more risky than COVID. 

The common refrain is that COVID vaccines get an exception because lives are at stake. I think this is a bandaid solution which ignores longterm repercussions. The anti-vaxxer who loses their job doesn't just crawl under a hole and hide. They go on the internet, fume and rage and become even more radicalized. At this point, the risk of accidentally grooming large-scale domestic terrorism is way more serious than a tiny increase of COVID deaths in a largely vaccinated population. Anyone who disagrees probably hasn't seen the kind of anti-left videos which have been trending on Youtube recently, replete with comments unironically advising each other to become terrorists and mass shooters in order to stop the globalized elite from taking over the world.

Hard Problem of Consciousness Proof

The Hard Problem of Consciousness asks why a subjective inner world (your mind) arises from objective physical processes (your brain). It's controversial because it's frequently misunderstood. People think it's about consciousness being caused by some supernatural thing other than your brain, so if scientists map the whole brain and correlate every physical process with every emotion, the problem no longer exists. This is a complete fallacy and misrepresentation of what the Hard Problem of Consciousness means. Many people who agree with the Hard Problem also believe your mind is completely based on physical deterministic processes in the brain and nothing else. The catch is: "The brain 100% causes the mind" does not mean "the brain 100% explains the mind". 

In order to prove consciousness is really an unsolved and possibly eternally unsolvable problem, I first need to establish what we really refer to as "consciousness", which I would rather refer to as "subjective inner mind" to reduce ambiguity. To do that, I will introduce a special attribute that no objective thing in the world can possibly have, then show that what I call "subjective inner mind" does have that attribute. That attribute is: Certainty. Specifically, 100% totally absolutely certainty beyond any doubt (even unreasonable doubt). 

Here are examples of things that are not 100% totally absolutely certain beyond any doubt (even unreasonable doubt): 

  • The Earth exists (maybe it's just a simulation)
  • You have a brain, made of neurons (maybe your whole life and the whole world is a dream and your real brain is made of something else)
  • You existed 1 second ago (You could be a simulation turned on just now, similar to "Last Thursdayism")
Anyway, you get the point. Literally no observable thing in the universe satisfies this "100% totally absolutely certain beyond all doubt (even unreasonable doubt)" attribute. 

Now you're wondering how in the world I'm going to prove that what I call "subjective inner mind" is 100% totally absolutely certain beyond all doubt. To clarify what I mean by "subjective inner mind" I'm going to ask you a question: 

Is it absolutely "100% totally absolutely certain beyond all doubt" that something exists or is happening in some way shape or form

  • Sure, the universe might be a simulation, but at least that simulation would exist.
  • Sure, you might not have a brain, but something that thinks it has a brain and feels like it's "you" is experiencing something at this moment
  • Sure, maybe you didn't exist 1 second ago, but at this very moment you are totally certain of feeling some experience in some way shape or form, even if you're not sure what physical form it takes. 
No matter what crazy conspiracy theory or Matrix theory you make up about how the universe really is, there is no getting around the undeniable fact that some experience of something is taking place right now. That thing/experience is your subjective inner mind, and it has an attribute of certainty which definitively separates it from any objective thing in the universe that could ever be observed. 

Therefore, even though it's right to say the brain causes the mind, you can't say the brain or brain activity is the mind. At best, you can say the two are perfectly correlated. Since the two are not literally the exact same thing, there's always going to be the question of how/why the subjective inner mind even exists in the first place.

Covid Vaccine Rant

To vaccinate the population against COVID-19 it seems most governments have designed policies that involve phasing in huge groups of people at once. For example in California, on 4/1/2021 everyone 50 years or older will become eligible; on 4/15/2021 everyone 16 years or older will be eligible. 

My question is why are there set days for expanding eligibility instead of a priority queue (or something similar)?

The problem with set days for suddenly expanding eligibility is two-fold: If it's too early then the at-need won't get it soon enough before being overrun by others; if it's too late then you momentarily hoard a surplus and didn't get the general population vaccinated as fast as you could've. On top of that, once the less-at-need people become eligible, there is no way to prioritize someone who's more-at-need and didn't get an appointment yet. 

Why not just have a priority queue where the most at-need group gets first dibs on an appointment date, then lower tiers get progressively lower priority "dibs". For example, say in general appointments are available up to 10 days in the future. You could make 65+ able to book 1-10 days ahead, 50+ able to book 1-7 days ahead and 16+ only able to book 1-4 days ahead. So at first only 65+ can make an appointment for day 10, but as that day gets closer, more people can book an appointment for that day. Such a system seems simpler, more efficient, and more moral; in fact it appears to do away with the flaws of the current system without introducing any downside at all. So, is this a classic case of government inefficiency, or can someone come up with a legitimate reason the current system is preferable? 

(Implementation detail: In the very beginning, only the most at-need group is eligible to ensure they fill up all the appointment slots. After that, everyone 16+ is "eligible" but of course the less at-need groups will be lower priority and will be unlikely to see any open slots until the more at-need groups have been fully vaccinated. As the more at-need groups become more vaccinated you can tweak the numbers of allowed lookahead days to give the less at-need groups more freedom to book in advance. For example, after most 50+ are vaccinated, then they only get first dibs for appointments 9 or 10 days in the future, and everyone else can look at days 1-8.)

Teletransportation paradox explained (again)

 I've written a previous article explaining how teleportation and/or mind uploading will actually be "the real you". But I realized it was hard to read, so I'm going for a simpler, condensed explanation in this article (with pictures). 

The essence of this "proof" is a very simple proof by induction common to mathematics. 

Imagine there are two brains, A and B. Brain A is your original brain. Brain B is a perfectly physically identical copy of your brain that was created/materialized in a new location. 

  1. Swapping a 1-atom chunk from each brain, won't result in your consciousness "jumping over" from brain A to brain B. 
  2. If swapping an X-atom chunk from each brain won't result in your consciousness "jumping over" and changing locations, then neither would swapping an X+1 atom chunk. For example, if in one case the swapped chunks were 1 trillion atoms big, and you hypothesize there is no "jumping over" in this case, it would be irrational to claim that there would have been a jumping over if the chunks had been just 1 atom bigger.  
  3. #1 establishes the base case, and #2 establishes the proof-by-induction ladder all the way to swapping the whole brain. Therefore, swapping your whole brain must be the same as not swapping anything at all. 
So copying yourself then doing nothing, is exactly the same as copying yourself and then swapping your bodies. Even from "your" point of view. This sounds like crazy talk, but if you disagree you'd have to poke a hole in the proof by induction outlined above, in which, as far as I know, there isn't any. 

One common theme for rebuttal would be to bring up the Sorites Paradox (aka, "when does a grain of sand become a heap of sand"). However, you'd then be claiming that as you gradually move more and more atoms over, your consciousness is gradually going more and more into the new brain. For example, you'd be saying that at 50% swap, your consciousness is half in the old brain, and half in the new brain. This doesn't make any scientific sense as there is no physical way for a consciousness to be magically telepathic and feel things from both brains at the same time. Remember both brains are physically identical in every single scenario. Therefore, if you agree a mind is caused by nothing more than its physical materials, there's no way for any of the minds in those brains to feel "partially dead" or "partially moved over". 

To understand why this is not a paradox, requires abandoning some very deeply rooted intuitions about consciousness: 
  • You are your physical brain: False. You are the information which is produced by the physical brain. Your consciousness is the information itself, not whatever substrate the information happens to be running on
  • There is a continuous self, aka "I think therefore I was": False. There's only "I think therefore I am". You can consider your present self to be a new consciousness that beliefs they're the old one from yesterday. There's no physical evidence for an extra thread of continuity to your past self any more than what your brain's memories are telling you to believe. 
Once you abandon the incorrect assumptions about consciousness, everything starts to make way more sense, and the paradoxes resolve themselves. I understand that my claims are extraordinary which require extraordinary evidence, but I believe the proof by induction is more than enough to satisfy this requirement. As the saying goes, “once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.”

P.S. the most common response to this argument I have found over the years, is people say "it doesn't make sense to see from two pairs of eyes at once". I am honestly baffled by this and do not understand why people believe this is implied by my argument. If this was your reaction, please re-read and understand the post. The fact that magical telepathy cannot exist is precisely why we can conclude there is nothing that needs to "jump over" in the first place (it's an illusion).
