It's fascinating to me that a pure element would have such immediate and significant effects on the human mind. I would think that this would generally require a more complex molecular shape that can fit with various receptors in the body and trigger the release of dopamine and other neurotransmitters.

Apparently, Xenon does this by acting as an antagonist of the N-methyl-D-aspartate (NMDA) receptor, a subtype of glutamate receptor, and also by enhancing the effect of ("potentiation of") gamma-aminobutyric acid (GABA). Other drugs that act along the NMDA pathway are Ketamine and Memantine (an Alzheimer's drug). And other drugs that act along the GABA pathway are Benzodiazepines (e.g., Diazepam, Lorazepam-- i.e,. Valium). And apparently Nitrous Oxide (N2O) uses both mechanisms as well.

      > It is caused by the anesthetic effect of certain gases at high partial pressure... Narcosis produces a state similar to drunkenness (alcohol intoxication), or nitrous oxide inhalation.

      > Except for helium and probably neon, all gases that can be breathed have a narcotic effect, although widely varying in degree. The effect is consistently greater for gases with a higher lipid solubility, and although the mechanism of this phenomenon is still not fully clear, there is good evidence that the two properties are mechanistically related.

    My understanding of mechanisms from a chemistry perspective is that the anesthetics mess with the phospholipid bilayer making up the cell membrane in a way that closes off receptors. So it makes intuitive sense that dissolving giant xenon molecules in a layer could mess with it from a pure physical perspective. What's weird, to my mind, is that other noble gases don't have any effect - you'd expect a gradient.

There is another post that is sounding an alarm on inert gas asphyxiation which I think is quite important but it's flagged, presumably because of a sidebar admonishment about drug addiction.

Breathing inert gasses is extremely dangerous. It is not like holding your breath: because the gas you inhale is free of oxygen, it actively pulls oxygen out of your blood. Instead of thinking about breath holding, think more like the USCSB videos where someone walks into a space with a nitrogen atmosphere and immediately drop unconscious, then someone goes in to save the first person (already knowing about the danger) and they both die. ( https://www.youtube.com/watch?v=f2ItJe2Incs ).

When narcotic gasses are used for anesthetic purposes they're used with a gas manifold that mixes in pure oxygen to achieve a gas mix that won't kill the subject. Even this is easy to get wrong, and a wrong mix due to a flat tank or an incorrect setting can kill someone very quickly and quietly.

It's also not clear to me how psychologically safe it is, I've seen at least one clearly unhinged person on twitter going on about their xenon use... but I dunno if the drug use lead to they psych issues or the psych issues lead the the drug use. or if their issue was just related to inadvertent oxygen deprivation as a side effect of their xenon use. Studies of anesthetic use may not tell us much about recreational use since they're presumably not dosing people daily or multiple times daily for weeks at a time. -- it's not like you can easily purchase single doses, that bottle isn't going to use itself!

In college I used a lot of nitrous. I got small cartridges and a “cracker” with a balloon. It was pretty euphoric.

I stopped after recording myself taking it. I was unconscious a lot longer than I remembered being, and even though I was probably never at risk of suffocating there were long periods where I didn’t see myself breathing. That was enough.

      Because they don't know better. It's not like we teach "safe consumption" in schools, and so most (particularly young) consumers of all possible kinds of drugs end up with cargo-culted consumption methods. Yes, Erowid etc. exist, but you need to know about that as well.

It's a shame xenon is an anesthetic. If it did not have that effect, one could pressure xenon until it was the same density as the body. It would still be a gas, and one could include some oxygen in it so one wouldn't suffocate (although breathing could be more laborious, perhaps require mechanical support).

Suspended in this gas, one could be subjected to much higher acceleration without injury, up the point that density differences in the body become important.

IsTom 6 days ago

Wouldn't it be the same as breathing any other nonreactive gas? Isn't this just symptoms of hypoxia?

  • lpribis 6 days ago

    No, xenon is a NMDA antagonist meaning it has dissociative/anaesthetic effects like ketamine or nitrous oxide.

    TFA talks about the effects coming on "within seconds" of inhalation, so it is clearly not just hypoxia which takes tens of seconds or minutes to manifest.

    • mrob 6 days ago

      Asphyxiation with inert gases causes hypoxia very quickly. It's not like holding your breath. Lungs don't actively pump oxygen; gases just diffuse along their partial pressure gradients. Air has higher partial pressure of oxygen than blood does, so the oxygen diffuses from the air to the blood. If you fill the lungs with inert gas the oxygen diffuses back out again. You're effectively breathing in reverse.

      Filling the lungs with vacuum has the same effect. You have about 5 to 10 seconds before you're incapacitated:

      https://en.wikipedia.org/wiki/Time_of_useful_consciousness

      • teraflop 6 days ago

        Even though xenon doesn't easily form "compounds" in the normal chemical sense, it does weakly interact with other molecules through van der Waals forces, which are strong enough to affect the functioning of various receptors in neurons.

      • lpribis 6 days ago

        I'm not very knowledgeable on this, but my understanding is that xenon can dissolve in the lipids in the brain and influence reactions in that state. This paper [1] seems to show that xenon can displace glycene in the NMDA receptors. The receptor is a "door" and glycene is one of the "keys" to open. By binding or interacting with the glycene site on the receptor, xenon keeps glycene from reaching the receptor, inhibiting it.

      • alan-hn 6 days ago

        Reactions don't need to happen, the magnesium ion is a single atom that interacts with the NMDA receptor to block it at specific potentials. When the postsynaptic neuron gets enough input at a synapse, there is enough change in the charge inside the cell where it allows the Mg2+ ion to be displaced from the pore to allow cations to pass through

        Our cells use single atoms, usually in the form of charged ions, on a regular basis and we would not survive without them

    Clearly the symptoms aren't the same as just holding your breath, which makes me think that it is not, in fact, completely nonreactive. (But I'm a total noob to biochemistry.) Similar to Nitrous Oxide, which definitely has a powerful psychedelic effect and is not at all simply hypoxia.

    • alan-hn 6 days ago

          Argon is basically a rounding error in atmospheric gases.

          Xenon has been the gas anesthetic of the future for a long time now. It does have one set of good qualities: it's not halogenated (like all common gas anesthetics), but it's nonflammable (there are very good anesthetic gases, like cyclopropane, that are extremely flammable and have thus been totally phased out of use), and because it's such a heavy atom, it essentially never leaves the atmosphere - no matter how much you use, you can always recapture it from the atmosphere.

          It's not particularly cheap, though.

    As with anything medical, the price of the item isn't just the item itself, it's purity plus that someone has verified and stamped off on it. I don't know much about argon, but for nitrous oxide, food grade is generally between 99% and 99.9% pure. If you want medical grade, the threshold is 99.99% pure or better depending on what you're doing.

      • DannyBee 5 days ago

        In the case of Argon, it's both inert and non-toxic. The main danger is that it's heavier than air (so you can asphyxiate yourself if you try).

        As such, "food" grade argon is actually less pure than industrial argon - food grade is 99.996 and industrial grade is 99.998

        The practical difference is what contaminants exist - because argon is non-reactive, in food grade argon they are just trying to remove contaminants you don't want in food.

        In industrial grade argon, mainly used for welding, almost any kind of impurity can cause issues, whether it would be "safe to eat" or not.

I find a lot of these casual drug use articles to be a bit naive on safety. “It does not cause metabolites or react” well it obviously modifies several biochemical processes in order to have an effect, who knows what long term effects it has on your brains computation.

    - "It’s best to say that from a safety perspective it probably won’t kill you straight away"

    It *will* kill you straight away–it's an asphyxiant gas, any mistake involving oxygen supply will kill you in a few minutes, or leave you incapacitated and brain-damaged for the rest of your life. It's somewhat more hazardous than most, because it's (substantially) heaver than air, and accumulates in lungs.

    (And you can be certain there will be mistakes, because a large subgroup of the users will be binge-drinking escapism addicts experimenting alone, drunk, self-administering this anesthetic out of a party balloon.

        • david-gpu 5 days ago

          > they showed us the correct method. It was simply to send the tank up in the elevator unattended—one undergrad pushing the "up" button and stepping out, the other waiting for it on the destination floor. Stupidly simple.

          That works great until somebody in an intermediate floor enters the elevator oblivious to the risk and suffocates.

            That's what service keys are for - with the key turned, the lift will go directly to the selected floor without stopping.

        Is because an elevator is a small confined space or is it because of some other unique property of an elevator?

        • lazide 5 days ago

          It is a small confined space that you have little control over your ability to escape or open up.

          A stairwell you can run up, or out a door. An elevator can get stuck - or just take awhile - and there is nothing you can do about it.

          Also an issue with liquid nitrogen, but that usually takes a little longer to sublimate.

          Dry ice is one of the few grocery store substances (in many areas) with a similar issue, but at least co2 causes a suffocation reflex we can feel. So less dangerous.

    That's exactly what I was going to bring up with this. As a doctor I just chuckled when it got to here

    > Xenon is considered “the perfect anesthetic” for 5 reasons:

    > It’s extremely fast-acting — xenon gas kicks into full effect within seconds

    > It wears off quickly — once the gas is removed, normal consciousness comes back within a minute or two

    > It doesn’t interact with other drugs

    > It leaves no lasting side effects or toxicity

    > The anesthetic state xenon induces is extraordinarily powerful

    The vast majority of drug incompatibilities are not a result of the physical interactions between the molecules. It's the undesirable effects that they exert in tandem on physiology. A vasodilator and a negative inotrope don't have to chemically react with each other to give a patient a very bad time.

    I will acknowledge that xenon does appear to have interesting effects, but nobody should be base their health and safety on what the author has written. Their analysis on its safety is far far far too superficial to be worth anything.

      > Bandera and his nazis

      Bandera was fighting against the Nazis by the end of the war. At any given time, he was doing what was prudent for his country and getting resources to fight the Cheka, because the Soviets were disappearing Ukrainians in the middle of the night and sending them to gulags.

      Appreciating Ukrainian cultural traditions is not political. "Slava Ukraini" should not be a political or offensive phrase, unless you are a genocidal maniac supporting Putin's mass murder.

      > a liberal attitude like yours.

      Lemkos then and now generally had a pretty high opinion of Bandera (they were forcibly resettled by the Soviets). Doing ether is not a particular indicator of a liberal attitude -- it is a traditional practice in Lemko society, and it was so during the time Bandera was alive. Ether is fun and enjoyable, and I like it better than alcohol. I don't think it changes your political designation. It is maybe a Calvinist/Puritan attitude to see the consumption of ether or alcohol as associated with political liberalism, are you perchance of American Protestant stock? This attitude is extremely alien to me.

        > "Slava Ukraini" should not be a political or offensive phrase, unless you are a genocidal maniac supporting Putin's mass murder.

        Ask the poles what do they think of it. Are they all "genocidal maniacs supporting Putin's mass murder"?

        Bandera and his OUN carried out massacres and ethnic cleansing of a hundred thousand Poles, plus we don't know how many Jews. It was the slogan of the OUN so yes it is a highly offensive phrase especially if you are Pole or Jew.

        I couldn't care less if modern Ukraine adopted it as a national slogan. If Germany decided to adopt "Sieg Heil" as a national slogan, that would still make think of Hitler every time I hear it even though Germany is now a democracy.

        > Lemkos then and now generally had a pretty high opinion of Bandera

        Some Germans still have a pretty high opinion of Hitler, some Italians of Mussolini. That doesn't make up for their crimes.

        > > a liberal attitude like yours.

        You happily partake in Xenon, ether and what not, I generally call this behavior that of a junkie, liberal was my way of being polite.

        • rabite 5 days ago

          The phrase "Slava Ukraini" predates the OUN by actual decades. There are plenty of people in Ukraine, particularly East Ukraine, that have personal objections to the mythos of Bandera as a national hero that still use the phrase, as it was coined in the Ukrainian War of Independence. Comparing it to "Sieg Heil" is utterly disingenuous. Regardless, your summary of Bandera and the OUN is delusionally ethnocentric and clearly biased against Ukraine.

          > I generally call this behavior that of a junkie

          and most people that voted in favor of prohibition would say that everyone that drinks alcohol must be a public drunkard, I guess. Usage of ether is a tradition on par with drinking in at least one part of the world. It is a little more dangerous, given ether's excessive flammability and low flash point, but inhaling some ether does not make anyone a junkie. America doesn't have a tradition of ether at all, and it is the only country where there are shambling masses of xylazine/fentanyl zombies defecating in the streets. Maybe you could all use a little more traditional ether consumption.

            LOL I'll introduce you to the fact that Sieg Heil originated in Germany around the 1900, way before the nazis got the power. The roman salute was used by the Roman empire, the earliest known use of the swastika dates the 4th centure BCE. Yet none of this symbols/gestures are accepted today, because the nazis spoiled them for everyone.

            > Regardless, your summary of Bandera and the OUN is selfish and ethnocentric.

            • racional 5 days ago

              Sieg Heil originated in Germany around the 1900, etc

              A broken analogy. The difference lies in the fact that these symbols were utterly obscure to German public before the Nazis introduced them in the early 1920s; though they had previous incarnations, in essence the Nazis reinvented them. In fact, they were so successful at it that most people are surprised to learn that these symbols had prior origins.

              The situation with "Slava Ukraini" is entirely different. It first appeared in a poem of Shevchenko in 1840, and gained widespread traction during the War of Independence. It was then co-opted by the OUN, but the point is, by that time it had its own "legs" as a slogan rooted in Ukrainian national consciousness, completely independent of Bandera and his program.

              And used today, it has no fascist connotations, and does not indicate support for Bandera or the OUN. That's just a simple fact. You obviously want the slogan to mean something different in the current context -- but we're talking about a country of 44 million people here, and if you have any interaction at all with this society, it's perfectly obvious and clear what they mean by it. I take their word over yours.

              The Poles have long gotten over all this history too, of course. They know what happened in those years, but they know that what's happening in the current day is infinitely more important. They know there's a fascist aggressor to the East which threatens their survival as a people, and it isn't Ukraine.

              Your attempts to conflate the slogan with a meaning it simply doesn't have are disingenuous. You're clearly not interested in what's historically accurate, or what describes the feelings and intents of people who use slogans like "Slava Ukraini" today.

              You're only interested in this stuff as scare imagery -- as a way to push people's buttons.

                That's BS. Do some research, check how many marches like this one[0] (clearly mimicking nazis and glorifying Bandera) there are in Ukraine. Check the countless pictures and videos showing elements of the AFU wearing nazi symbology. Check what is the role of fascist militias like Azov and neo-nazi parties like Svoboda in the 2014's Maidan.

                What evidence do you have to support that symbology taken straight from Bandera period has no relationship with him?

                That's bullshit as well, and you know it. To this day Poland comdemns Ukraine's commeration of Bandera & co.[1] That's a constant source of friction between the two countries, which are only united at the moment because of Russia.

                The real problem with Ukraine as a nation is that the only national cultural identity they could find is rooted in collaborationism with the nazis, ethnical extermination and hatred for the URSS. Not a great base to start from.

                  Check what is the role of fascist militias like Azov in the 2014's Maidan.

                  Azov did not exist at the time of Maidan.

        By which you must mean his issuing the Act of Restoration of the Ukrainian State, which famously states:

          3. The newly formed Ukrainian state will work closely with the National-Socialist Greater Germany, under the leadership of its leader Adolf Hitler which is forming a new order in Europe and the world and is helping the Ukrainian People to free itself from Moscovite occupation.
        • rabite 5 days ago

          Yes, absolutely, the Soviet Union and its Secret Police were an active threat to Ukrainians every day. Adolf Hitler was not.

          Though Bandera did work with the Nazis, he later worked against them. They weren't ideologically into Nazism.

          Even Karaite Jews in Ukraine joined SS regiments at some points. They didn't love Hitler, everyone knew Hitler was a stinker. They were just more immediately concerned with the immediate threat of forced starvation or torture in a gulag.

              Yes. It was prudent to do anything to save Ukraine. Absolutely. If you love your country you'd deal with the devil himself to save it from what Russia was doing.

              10 million people died in Genrikh Yagoda's torture chambers. Another 5 million starved to death in the holodomor.

              Hitler was bad, sure, but only a third as bad as the Bolsheviks. And about half of those 15 million deaths happened in Ukraine, and Bandera's fiduciary duty was to fellow Ukrainians, not to some foreign nation. If you had to pick a side (and Bandera did) it was best to go with Hitler.

              • racional 5 days ago

                10 million people died in Genrikh Yagoda's torture chambers.

                These are some wildly inflated numbers you're posting here. Total estimates for the number of persons killed in pre-war political repressions in the USSR top out at 1 million or so. I'm not sure what Ukraine's exact number is, but (in asserting that it was "about half" of 10M) you're easily inflating the true number by a factor of at least 10x here. Likely closer to 20x.

                Why are you doing this?

                • rabite 5 days ago

                  Wikipedia cites the Holodomor as 5 million. That was mostly in East Ukraine. That's most of the half. The other 2.5 million were from gulags.

                  There were 20 million+ excess deaths, of which 10 million are commonly attributed to Yagoda:

                  • racional 4 days ago

                    Wikipedia cites the Holodomor

                    You cited, as an encyclopedic fact, 10M as having perished specifically "Yagoda's torture chambers" per your words, which can only refer to NKVD (or otherwise "political") persecutions -- not the various deportations en masse or the Holodomor. The WP page you cited confirms upper bound for the former set of excess fatalaties (i.e. the one that you were explicitly referencing) at 770k -- which we shall charitably round up to 1M for the sake of "civility" here -- for the entire USSR during the pre-war era.

                    Far short of the 10M figure you are introducing for whatever imaginitive and creative purposes.

                    Again: 10M in this category -- the number who perished "Yagoda's torture chambers" throughout the USSR before the start of the war; and "about half" being in Ukraine; or around 5M, is the number you put forth -- apparently for the nifty rhetorical effect you thought it might bring.

                    Whereas the historical consensus for this category is <400k.

                      I didn't introduce the 10M figure, I linked an example article where it was used (the Ynetnews one) -- it is a common number I have seen of those who died in Soviet prisons. Maybe not specifically those who were captured by the NKVD -- but I think a lot of people were dropping dead who were also not political prisoners.

                      > 10M in this category -- the number who perished "Yagoda's torture chambers" throughout the USSR before the start of the war; and "about half" being in Ukraine;

                      No -- I said about half of these excess deaths were in Ukraine, most of that half being made up of the 5 million people killed in the Holodomor.

                      I'm sorry I don't have perfectly legible accounting of the millions of people Stalin killed in Ukraine, but with the lower bound being in the millions I don't think saying 7.5 million people killed in Ukraine is unreasonable. The Holodomor killed 5 million and then there's assuredly another 2.5 million made up in further excess deaths there somewhere. I don't know if it is perfectly accurate and I don't care. These were the people who Bandera had a fiduciary duty to protect, as a leader of Ukrainians. I don't support the evil things that happened in Volhyn and Galicia, but those things had a historical context where there was a credible threat of millions more lives of his countrymen on the line. Tough choices had to be made and he made them.

                          Okay. Let's pretend the Soviets killed nobody in Ukraine other than the Holodomor. That's 5 million people. The credible threat of millions more being butchered by the Soviets was real. At this point, we are disputing small fractions of the total deaths. I don't care if it was only 5 million, though it was millions more.

                            There is no Ukrainian/Soviet distinction. Ukrainians were Soviet at the time. Ukraine was historically part of the Russian empire and only split very briefly after the revolution. You are trying to promote the idea of a split between Russia and Ukraine that didn't certainly exist at the time.

                            Putting that aside, nobody "killed" 5 million people. Killed certainly isn't the correct term, as the Holodomor was about deaths by starving and not by shooting. We're talking about mismanagement, not murders. Otherwise we'd have to consider every death caused by government mismanagement as murder.

                            When a homeless dies for the cold do you consider him to have been killed by his country?

                            When someone dies because they couldn't afford insuline, is it a murder by the government?

                            When a worker dies in a factory accident, was he killed by an unequal economic system?

                            Between 17500 and 46500 homeless died in the USA in 2018 alone[0], was that mass murder by the government? No? Then the Holodomor wasn't a genocide.

                            By the way, get your numbers straight again, it's 3.9 millions[1], not 5.

    I think this is an unnecessarily polarized admonition. Alcohol is arguably more than possibly-lethal, but many people exercise a reasonable risk calculus that allows them to enjoy it, and even enjoy it to a low level to moderate excess (on occasion), and that doesn't necessarily indicate pathological drug abuse.

    An unusual medically-safe (in medical contexts) anesthetic generating curiosity about recreational effects and safe use is not unreasonable, and having that curiosity certainly doesn't imply that someone is "not ok!"

    I'm not saying that Xenon isn't exotic; it likely takes someone with a strong background in less-dangerous inhalant usage (and deep pockets) to use it safely. But there are plenty of exotic substances that people use safely and sanely throughout the world, and telling people off for having interest drawn from a (reasonably balanced, I would say) source ain't the business.

      It's a heavier-than-air asphyxiant and the contexts are not medical. It takes somewhat rose-tinted glasses to assume every person abusing this anesthetic will do so safely, under professional supervision, in some expensive clinic. Or that the anesthetic spas will be competently regulated and ethical.

      Inert gas asphyxiation is instant death.

        You're wrong.

        Asphyxiation is a "deprivation of oxygen that can result in unconsciousness and often death"

        But it is not instant death, otherwise we wouldn't be talking about people doing it recreationally.

    Couldn't you say the same about any extreme activity (like going to the moon or base jumping or extreme stuntmen etc)?

    Some people seek out risk because it makes life worth living.

    Life is finite anyways so even if you are very careful you'll end up dead just like the rest of us.

    That's an awful lot of judgement being passed from someone who I assume has zero connection with the medical industry or addiction treatment

    I'm not a xenon user, but I completely disagree with what you've said here. What is your point, that because xenon is hard to make it's an insane person's drug? You're implying a huge level of risk but TFA outright states that xenon is incredibly safe, which can't be said for ingesting carcinogens from combusted cannabis, or from drinking alcohol which can kill you in a single night pretty easily. Are you saying TFA is lying about the chemical safety of inhaling xenon?

    There’s nothing possibly lethal about 30 seconds of breathing pure Xenon unless you do it standing on a tightrope.

    A desire to experiment with a relatively safe psychoactive on a 30 second basis doesn’t come near “pathological”.

      People do die using asphyxiant gasses recreationally. Xenon's much greater density and narcotic potential may make it more dangerous than nitrous oxide.

> Xenon is unique among psychedelic drugs because it’s a pure element. It leaves the body exactly as it entered, completely unchanged.

I very doubt it is true. The article poorly hand waves later that a brain without oxygen will starve.

I bet shooting this crap for some short term high will burn your brain cells, even if mixed with oxygen.

  • RIMR 6 days ago

    Xenon gas is a pure element. It absolutely is going to leave your body exactly the way it entered, because your body has absolutely no ability to break down a pure non-reactive element into anything.

    You seem to be responding to this as if it is saying that your brain is immune to injury from Xenon abuse, which is never a claim that the article made. It is clearly stated that oxygen deprivation through Xenon inhalation can cause death.

    Now, 30 seconds of oxygen deprivation is sure to cause your brain to "starve" in the sense that oxygen levels will drop enough to affect your consciousness, but that's absolutely not enough oxygen deprivation to cause brain damage, given that the general method is to trip off of a single inhale, similarly to how Nitrous Oxide is used recreationally.

  • alan-hn 6 days ago

    That's absolutely not true. It is already used in medical practice and mixing with oxygen, similar to how laughing gas is used, prevents hypoxia. These things are easy to google if you actually care to look

    A magnet will pass by a hard drive and emerge totally unchanged. It doesn't mean the hard drive was not changed

    • snaeker58 5 days ago

      I wouldn’t use such analogies on wildly unrelated subjects.

      Saying „The long term effects of Xenon on the human body and brain are still mostly undocumented when it comes to repeated recreational use.“ sounds so much better!

      Especially since almost all common magnets don’t actually effect a hard drives functionality. The internet states you need a magnet with a force of 0,5kg to actually cause data loss. So we’re talking a large neodymium magnet. Which makes this analogy even worse.

      It’s honestly incredibly how much your analogy upsets me!

      • idiotsecant 5 days ago

        Sounds like a you problem, the analogy is fine. Just because the gas emerges unchanged does not mean the body through which it passed was.

    • rvba 4 days ago

      Very good analogy!

    You should compare it with oxygen tents used to simulate training at high elevation. The risk of damage is more-documented from those compared to argon and xenon.

These days we have some theory about this. See Stuart Hameroff MD, a Professor of Anesthesiology and Psychology, and Director of the Center for Consciousness Studies at the University of Arizona.

To sum it up from my limited understanding: This disturbs the quantum coherance in the microtubelies in all cells (But mostly nurons) which is needed for consciousness to "limit" itself to a identity.

  • k8sagic 5 days ago

    Consiousness is a emerging feature of our brains complexity.

    The way this dude throws around quantum and co is just esotherical.

    Ummmm what?

    • Dachande663 5 days ago

      Hameroff is one of those common pseudo-psy frauds. Dawkins hit the nail on the head when he said consciousness is hard to grasp and understand so everytime something in science comes along that is also hard to grasp, people latch on to it as an explanation. 70s it was chaos theory, then everyone switch to quantum entanglement, and already seeing it leak into AGI.

        I recall coming across him before due to his extensive collaboration with Penrose. Typifies the thin line between genius and bonkers.

      • Arjuna144 5 days ago

        No no, Dawkins is just a old scientist and even though I admire him, he is just repeating the same old lines. These days there is research and qunatum effects in the structures of microtubelins was shown by other research groups also:

        https://pubs.acs.org/doi/10.1021/acs.jpcb.3c07936

        It is best to really do the research and not rely on people who already have made up their mind (that Dawkins guy for example seems like he really wants Materialism to be true).

        • robbiep 5 days ago

          You’re already polling way over what you’ve just said, though.

          There is no doubt that small structures exhibit quantum effects. There is absolutely no demonstrable relationship between small things exhibiting quantum effects and consciousness.

          You give your whole game away when you say

          ’which is needed for consciousness to "limit" itself to an identity.’

          This is actually mysticism. You’re already making absolutely extreme claims for what you believe consciousness to be.

          It may well be that consciousness is ‘in the microtubules’. But today we have no evidence of this. Nor do we have effective understandings of why anaesthetic drugs work (as opposed to, say, our mechanistic understanding of how opioids cause analgesia, or other pharmapsychophysiological relationships).

          Keep an open mind, but don’t let your brain fall out

          • Arjuna144 4 days ago

            You are right, what I claimed is byond the current scope of science. It is a bit like saying 'A brain can "see" an apple even when the eyes are closed" (alluding to what we call "imagination"). You _know_ it can, but science can not prove it. It is based on your very own experience

      • snaeker58 5 days ago

        Yeah this type of madness is rampant when it comes to AGI believers, always makes me want to drive a nail in my hand.
