[@letsomethingshine]

Dr. Anil Seth certainly is a very intelligent, insightful, and productive individual. However, I fear the last point of the conversation went astray. Just because it took so long to us humans to evolve muscles the way they are today, does not mean we could not replicate the effects and functions of muscles with silicon and metal. I believe AI has a very good opportunity of being allowed quaila-experiences and even surpass humanity in terms of “consciousness level” as it already has in information processing speed.

[@MandolinGuy530]

@@letsomethingshine I'm of the view that if we take our bodies and our conscious experience to all be purely physical things, then it stands to reason that given enough time we should be able to replicate those things exactly using different materials. If people pose some barrier for why we will only ever have soft AI, you'd need to account for what this barrier is.

[@kornklown420]

@@letsomethingshine I agree with you completely. I'd argue that currently the only thing holding AI back is the architecture it is built on. When people are critical of the ability of current AI, it's important to remember that current AI is built on general use computer architecture, which causes it to be exponentially less efficient than the human brain (it uses an enormous amount of power to maintain it's neural networks). And because of this the neural networks are entirely implemented in code. Currently there are companies working on architectures specifically geared towards AI neural networks, as well as companies working on bringing back analog computing in the form of analog microchips. As of right now the limitations of existing hardware, which again is general use and not even remotely optimized for AI, we can't get much further than we currently are. The second we create new architecture to optimize AI, we are going to see a boom that no one is ready for. And when AI does reach a level of consciousness on par with our own, we likely won't even realize it, and no doubt people will try to fight back against the idea with the same shallow arguments that "machines can't become conscious".

[@je-nas]

Strong atheist here. Dr. Anil Seth started so well explaining what consciousness is and why it’s so bizarre. Then I got REALLY frustrated when he made that so common, but so obviously misguided comparison with life: "oh, we also thought life had to be immaterial, elan vital, etc." As if it wasn’t FULLY OBVIOUS that the only reason we thought that, was precisely because of consciousness. The intuition behind elan vital is THE EXACT SAME INTUITION behind the seemingly immateriality of consciousness. There’s no separated “life intuition” that got “solved” by a materialistic explanation - rather, the elan vital intuition (pretty much an intuition about anima, spirit, that is, the consciousness whose intentionality animates the body; the biblical “breath of life”) got put aside and recast as just the consciousness problem. Edit: that said, all that follows is pretty awesome!

Psychedelics have a great potential. The first time I tried them they saved me from committing suicide. They also greatly improved my depression and social anxiety, and made me more conscious, and aware, of what’s going on both within and around me on a daily basis.

[@MichaelLeightonsKarlyPilkboys]

I studied neuroscience at Sussex and unfortunately didn't get taught by Anil Seth (I focused more on cell signalling, disease, anatomy etc.) but my friends who had him said his lectures were fascinating and were always excited for his classes. Feel like I missed an opportunity so this podcast is greatly appreciated.

[@HarryNicNicholas]

maybe you can throw light (!) on a question that's bugged me, signals (colour, taste, smell) get sent to the brain by ionising chemicals (chlorine, potassium, sodium i believe) which makes for an electrical signal, but how does the actual data, the colour information, what form does that take? with a computer it would be binary data, but presumably the brain uses signal strength? wavelength? amplitude? i've asked this many times but never got an answer....??

[@MichaelLeightonsKarlyPilkboys]

@@HarryNicNicholas You’re testing my memory! Been a long time since I did senses and vision was the most complex/unique for me. I’m far from an expert (plus I think visual processing is far from fully understood anyway) so forgive any potential errors or oversimplicity. There are many competing theories in exactly how this is done, but I believe the following is a somewhat accurate representation. The short version: the retina has a corresponding ‘map’ in the visual cortex, where each cortex cell is activated by its respective photoreceptor. The colour wavelengths are differentiated as they activate multiple photoreceptors forming a specific pattern of activation, and this information is transmitted to the visual cortex via electrical impulses, corresponding to the spatial arrangement of light on the retina. This is how the brain interprets different wavelengths of light. Long version: Multiple cones in the retina (the photoreceptors that detect colour) are activated by different wavelengths of light, and it’s that relative activation that creates a topographic impression of the light (individual cones don’t actually detect colour, it’s dependent on which ones are activated relative to one another to generate that information). Cone activation ultimately generates an electrical charge (vision is slightly different from other sense receptors in the way it does this, but not super relevant) and the electrical charge (via some processing along the way) makes its way to the visual cortex in the back of the brain, where it activates its corresponding neuron in a topographic map of the cortex. Think of it like keys on a piano - if you want to create an emotional sound, you wouldn’t play one note, you’d play a chord (comprised of multiple notes). An individual key can’t express sadness for instance, but multiple played together can. Similarly, colour information can’t be processed unless multiple cones are activated and the way the activation of cones is mapped across the retina reflects the wavelength of light (red has the longest wavelength, and so will activate more cones in a different relative pattern than violet, for instance). Very simplistically, each cone has its own neural ‘pathway’ to the visual cortex, the same way each piano key activates a specific hammer that strikes a specific string. So while it isn’t the keys themselves that create the sound, they interpret the input (the shape of the hand pressing on them) and their activation of a specific combination of keys produces a corresponding 'mapped' reaction inside the piano that ‘interprets’ the input to produce the specific sound that can only be produced by that specific input. Replace the shape of the hand with wavelengths of light, the hammer with an electrical impulse, and the piano strings with neurons in the visual cortex and it’s a roughly comparable analogy to how the brain interprets colour.

[@HarryNicNicholas]

@@MichaelLeightonsKarlyPilkboys sorry, i'm not being clear, i understand the mechanics of vision, it's how the actual DATA gets moved around, like i say in a computer it's an electrical signal in the form of binary, in the brain it's an electrical signal in the form of _____________ fill in the blank... see my other comment here about objects and light having no instrinsic colour.

[@MichaelLeightonsKarlyPilkboys]

​@@HarryNicNicholas Oh I see, do you mean in terms of how the action potential works? In a sense it's binary as there is either an action potential or there isn't. Sodium and potassium move down their electrochemical gradient across the cell membrane to depolarize the cell (although it's hyperpolarization in photoreceptors) to trigger an action potential, and it's essentially an 'on' signal or no signal. In that sense the data is communicated in a binary fashion, rather than through strength of signal (a cell is either depolarized/hyperpolarized or it's not)

[@Presage451]

[@electronmess]

For a sound engineer by profession, the green needle/brainstorm illusion seems to me the case of shifting focus between so-called overtones, undertones, while being led by dominant frequencies. Possibly a related phenomena is the Shepard tone, if anyone's familiar with it. Within a single sound, you have an entire spectrum of frequencies present. Some dominant, some quieter. If a sound contains frequencies all playing "the same amount", it's starts to sound like a random (white) noise. If you play a same note on two different instruments, you can recognize their different timbres. How? The dominant frequency (the note being played) is the same for both after all. It's (mostly) the overtones and undertones (frequencies below and above the dominant, which play more quietly) that make it so you can differentiate between a violin or a piano. My thinking is, in the illusion, dominant frequencies contributing to both words are strongly represented. They compete for the dominant frequency positions. They're "sticking out" with their higher amplitudes. What does the heavy lifting, I think, are the overtones and undertones. There you'll find most or the information contributing to the words. Notice how "brainstorm" sounds darker, lower pitched, where as "green needle" is whistling high up. Most of the word brainstorm's is at the bottom of the spectrum, needle the opposite. And our brain is, at one given time, either focusing mostly at the bottom, or mostly at the top. In a same way you shift focus on a bass guitar part in a song one second, and then shift focus on a high pitch flute solo later. Of course frequency content alone doesn't "create words". There's a coincidental alignment of information in the time axis as well. This is due to the sound content shape or "envelope", the rate of energy change at a given frequency. This makes transients, the beginning of words, of syllables, for how long they sustain and how quickly they fade out.

I didn't have hope from healing from 3 decades of PTSD until a therapist introduced me to psychedelics. One time I was at CSI Con and I told Richard Dawkins about how you can see 4D space inside your head with psychedelics. I asked, if we evolved to see in 3D, how is it possible to see in 4D, and he said "That's a really good question, I'll have to think about that."

@@christopherhamilton3621 Well obviously the word is used as a hyperboly. In my view materialistic philosophies have been refuted sucesfully but I am sure people will differ in their conviction. I can't go into much depth in KZbin comments I'm afraid. But I can say that when someone is expressing skepticism and calls perception 'hallucinatory' and in their next sentence talks about scientific and mathematical assumptions as if they are true (insinuating more true than our perception) they have failed to notice that all scientific and mathematical knowledge is founded on our perception. Founded here is used as a phenomenological term which means that it has been discovered (not assumed, discovered) to be dependant on the phenomenon as it appears to the senses.

I was under the impression that we have good reason to believe that more bottom up sensory data was being factored into our model of reality, when we are on psychedelics. This concept perfectly maps onto my personal experiences, insofar as when I look at a sunset on acid (early trip, or post peak, so not when having a full blown “what/where/who am I?”, moment) I can see the green, I can see much more of the reality of the scene, the kind of reality that artists need to include in order to create a convincing depiction. When I’m sober, using what Dr. Seth refers to as the controlled hallucination, it’s just… “orangey” with some read and purples perhaps, but this sober representation of the sunset feels very much like a optimal, practical depiction, rather than a more lossless, and “accurate” depiction of the actual wavelengths. I believe this also applies to many of our other sensory experiences when on acid. Now obviously your top down processing is also running in overdrive when on acid, but I feel this accounts for the pink elephants and bioluminescent jellyfish Angels, as opposed to things like the richer pallet of colours and more pronounced distinctions between light and shadow.

[@Chucklzzz]

This is fascinating to look at through a philosophical and scientific way. I remember very clearly, when my father was teaching me art as a kid (He has his degree in art) He always told me, "Paint what you see, not what you think you see." And I was able to look at a leaf, and a leaf is green, but it's not really. It's a huge variety of reds, blues, yellows, whites, greys in such a complex detail, that it just seemed impossible to me to actually be able to achieve it. It blows my mind, the level of understanding and talent that artists have.

I came across alot of great research and some topics mensioned in this discussion. It is hard trying to explain consciousness and perception and i have a view that many do not get as i have experienced many of these things physically and through research . Also experienced the feeling of pure hapiness he got from the drug just before i had a seizure before. I was the perfect subject for learning more but i didnt want to be a lab rat so i learnt and researched myself. I attempted to use my MRI scan and put it through a 3d printer to get a model of my own brain. The printer was overbooked but so thankful another person did it a year later in another university not connected but now this technology is used and can change peoples lives .I was told many times why study art when i should study neurology as i was pasionate but i wanted to do both.

[@alexlarsen6413]

What type of epilepsy do you have, if you don't mind? And if they found a cure, like a real cure for it, not just drugs to manage the symptoms, would you take it? I'm asking because I've come across people suffering from epilepsy, sometimes quite a severe form of it, but at the same time it's become part of them...their identity I guess, that they've answered; no, they wouldn't take the cure. Must mention those were very rare cases, however frequent enough to at least become noticeable. Another caveat is, this was my experience so it is anecdotal.

[@xpressivebex7162]

@@alexlarsen6413 thank you for your comment. You are right there is no cure . My little brother had the most severe type of childhood epilepsy (think it begins with an L) he was not supposed to live past 9 and had more than 10 seizures in one day. Spent my childhood watching him in hospitals. He is now 32 and grown out of it. I was diagnosed when 19 I grew into it , luckily wasn't same type mine is rare as I have few different types of seizures and even professionals don't know really depends on individual case. Long story short i found out I was born with a dint in my head when I was born and due to this I am almost blind in one eye and always had migraines. I never responded to meds either . The answer to your question is , although it is difficult to live in this world with the disabilities not to mention the stress , I am really lucky I only have a couple a month and I have an amazing son . I wouldn't change my experience and understanding as the way my brain works is part of who I am if that makes sense. The way I think and do things is my identity in a sense I am an artist because I have perspectives to show people it makes me unique I wouldn't take the cure I av asked myself this question few times in past 10 years. It's like the butterfly effect concept. also feel the same when I lost my mother at 13 that moment was important to direct my life in so many decisions I made next . It's hard to imagine life without when you just live with what your given. Thank you for your message really appreciate your comment it made me think . I focus on quality of life ATM there are many pros and cons to everything but you learn to live with what you have. I have healthier lifestyle as I have no choice e.g drink water, sleep exercise but the fact I have a guideline is actually helpful . The thing that throws me off the most is wondering if people would treat you differently if you didn't have epilepsy . Also interesting I look as though I workout and live extremely healthy so it's hard for people to get I have epilepsy as they don't see my seizures or mental problems. There is so much stigma with epilepsy I am not photosensitive but sun can trigger me but ppl don't really know much about it. Plus don't like to say sometimes . Some strangers don't know anything so I appreciate that I am healthy enough to advocate and help others who suffered a lot like my lil bro who had to learn to walk n talk again . So I must remain humble everyone has struggles. I can hope I will grow out of it but not sure. They still think me n my bros are connected so either it's, genetic connection, I have migralepsy as my migraines always been bad and triggered into seizures while growing or it's not epileptic and my brain neurons are messed up from trauma of abuse or losing a parent young. My body seizures when it's protecting itself subconsciously which is why sum can be triggered by PTSD it's a form of self defence. I saw this in research just a memory can do this but hard to prove so here I am 15 years later and they refuse to aknowledge that being drugged up doesn't work for everyone . I constantly have to show I am taking precautions as I live more natural but it's worth it. Every scan n test comes back clear so far they can't pick up what's happening unless I have a seizure during and then I'd be moving to much hense how important 3d printing is to the neurology field. If they don't know I don't am just an interesting case to them . All I can do is try live as best I can. I have tried over 25 different meds n treatments I have accepted some just have epilepsy for different reasons and it isn't a burden always. I wouldn't change me maybe my answer would be different if I was severe like my brothers but I am fortunate tbh. Also in a sense I think my epilepsy is more of a mechanism keeping my body alive but short circuits like electrics when it's going through too much . Hope this message answers your question. Sorry for long winded message . Hope you have a blessed day .p.s as much as antidotal is not evidence alone which frustrated me in my degree in most cases it is important to collect data from those who have experience so your view is way more valuable than you think just meeting someone who lives with similar things can change others lives so I appreciate your opinion its totally validated and needed in health

I think the last point of the conversation went astray. Just because it took so long to us humans to evolve muscles the way they are today, does not mean we could not replicate the effects and functions of muscles with silicon and metal. I believe AI has a very good opportunity of being allowed quaila-experiences and even surpass humanity in terms of “consciousness level” as it already has in information processing.

[@myothersoul1953]

We can replicate the movements of muscles with silicon and metal but those machines don't have a pulse. They don't have a pulse because how they produce movement is very different from how a muscle produces movement. The properties of any system depends on it's material components. Just because a system does one thing similar to another system doesn't mean that all the other properties of the two systems are the same. If semiconductors could have experiences they would probably be very different from the experiences we have. They might even be so different that they aren't even experiences.

[@LennY71]

Well the point was not that we can't develop artificial muscles, but that the training time would be too long. The current models are trained for a year at "the speed of electricity" on pre recorded data. But to learn in the real world the model must experience the world with its sensors, take an action like taking a step with its artificial muscels, and see the results of this action. This online learning can't be done that fast and the human brain comes "pretrained" with this kind of training from millions of years of evolution.

[@i1337Thinker]

Here's another illusion that shows something similar: If you have an animation of tv noise, with enough patterns in it, if you repeatedly tell yourself a shape such as "triangle" you'll see that you begin perceiving a triangle in the animation. The lesson learned from this experience is that our brains comprehend words without our permission, therefore we should be mindful of what we say to eachother.

[@bike4aday]

The world is neither just outside nor just inside... it's actually far different from any way we currently think about things normally. These kinds of conversations are definitely heading in the right direction and I love it. Anil Seth is a great guest. I'm happy for you Alex and that these podcasts are becoming so successful.

The brainstorm toy pulses color 3 times to the rythym of the syllables in "green needle" maybe that visual cue reinforces the perception of those words when you expect them

I remember reading a theory that monet had cataracts which affected his vision and color perception. So he wasn't painting his 'feelings' or impression of the scene, but he was painting what he actually saw, it's just that his vision was messed up!

[@whenimmanicimgodly4228]

1:20:26 I completely agree here. I used psychedelics a lot when I was young (and still do, though mostly just microdosing and not really intense trips anymore) and it's so beautiful and so hard to grasp with words at the same time. It's a magical feeling to have and unless you've expierenced it you really could never understand to what extent it can change your perception of the world. Psychedelics took me from a dark place (admittedly) and helped me see rhe light in the world, I wish I could thank them because it truly did help me. I was an addict for a long time, depressed and other issues; and that's all I knew. These helped me open my mind up and I think he best way I can describe how they affect me is they "make me feel like a kid again" as in, it makes me want to color and run and dance and play and just be happy, it brings back that old childlike instinct and enjoyment for a while, and I think it truly can be very helpful for people who have seen a lot. I hope one day we have better research and doctors that can use these psychedelic tools more frequently, rather than these addiction rattled pill bottles we have to take every day.

[@CassandraEvergreen]

Psilocybin became legal in Australia to be prescribed to mental health patients with certain conditions (like depression), by a psychologist, in February this year 😊 But I think it's only allowed to be used if the majority of all other medications haven't worked. Still, it's a start.

[@whenimmanicimgodly4228]

@CassandraEvergreen good luck! I'd also look into ketamine treatments. While they are expensive, I personally find them to be way more helpful depression and anxiety. One session and was good all year

You should do a podcast episode with David Eagleman. He's also a neuroscientist, but with different views on consciousness

[@TilmanBaumann]

1:36:39 The misconception is that the Turing test is a test of consciousness. It's not, it's a test if mechanisms can fool us into thinking the other is a person. Consciousness-mimicry is an ethical question in the sense that we have do confront a discrepancy of our feelings and moral feelings with a less tangible reality.

Very Interesting, I did modules on sensory systems and perception as part of my degree. Some of what is described here we were told is termed Colour Constancy and light constancy which was developed (selected) to detect objects and colours in different light conditions including things like dusk etc. If I remember correctly the colour was needed as a means to detect ripeness of food and differentiate possible poisonous berries. From what we were taught the senses and the brain use something like a differential system where it processes cone information from adjacent visual fields and do something equivalent to dividing one by the other and the resulting output would determine the colour perception (eg 1/2 is the same colour as 4/8), this is simplified however unless you program an AI to do similar operations it may have very different perceptions.

[@inrisalvatore9520]

But it only demonstrates the correlation to the mental perception. It doesn't show us how the material brain creates the mind itself.

Regarding the brain storm/green needle toy. You can also do brain needle and green storm.

[@Fake_Robot]

Every conversation I see about objective vs. subjective reality is only about the most basic level of “is there a table there? Is your green the same as my green?” The more important and more frustrating conversation needed is for events and social perception, e.g., eyewitness testimony, or moments where there’s not just two people at a table but two people walking down a busy sidewalk whose sensory fields are crowded and the ability to capture the totality is limited. THEN, the differences become more pronounced and we learn the subjective experience is not at all a reliable record of the truth.

[@jozefglemp8011]

this one blew my artist mind

[@AnotherRoof]

I can switch between blue/black and white/gold on the dress. Cover up the bottom of the image, and the white/gold becomes a plausible interpretation, then slowly reveal the bottom and let that perception remain. Do the opposite for blue/black where covering the top allows you to interpret the bottom as blue/black. Do it a few times and you can flip between them at will. But no matter how hard I try, I absolutely *cannot* hear "green needle". Even with the pitch shifting that people do, my brain just hears brainstorm at the original pitch. I also have a video on my channel about the differences between deductive, inductive, and abductive reasoning!

Brilliant podcast. I’ve been a fan of Alex for a few years. My worldview is completely different. I’m Christian and an MA theology student and theologically it takes my mind to passages like Mark 11:24 where belief and expectation play a huge role in prayer. Furthermore, other passages that speak of not doubting are scattered everywhere and hold a real sense of expectancy. Great convo. This is just great food for thought. Thanks dude.

Objects perceived as 'orange' often comprise a wide range of non-orange colours (red, yellow, a variety of browns, even white and black) while true/solid orange is quite narrowly defined. I have analyzed photos of oranges and orange cloth where only a small minority of pixels were actually orange. And yet combining them makes a whole that is clearly 'orange'. Although I am not an artist myself, I believe artists routinely 'see colours for what they are'. ETA: In this way, in the original photo of 'The Dress' it's shades of blue and shades of brown, and not either 'blue and black' or 'white and gold'.

[@laidenday7277]

I think what can be added here is that coquincidental choas/probability experienced in life that makes me speculate about a higher power is actually probably most likely complex intricut nature or quantum principles which we have learned to adapt with bc we need our environment to exist.

Great episode again! What I don't get is in virtue of what an AI running on hardware is not embodied in the world. If necessary, take the leap to add video camera footage with time and geolocation info to the inputs of an AI.

[@johngaunce]

In regards to Nagel and the way philosophers speak about experience, I think people let language wrap them up in circles. We don't experience redness, we experience a red object (accurately or not). Saying we experience redness is like saying we experience experience... which is just a spiraling self-referential chasm. After all, what is redness? It's our experience of red. If we dispense with that, so many or the allegedly impenetrable problems of consciousness go away. The question "what's it like to be a bat?" becomes a request for metaphor as opposed to a request for some actual data.
