Call me crazy if you like, but it seems to me that the human tissue in the rat did not control the rat at all. It was integrated into the rat brain. It's like adding a a video capture card to your PC, it doesn't control the computer, it becomes part of it and augments its capabilities. The experiments with blue light demonstrate this integration.
Since the human tissue was responding to external stimuli, I think comparing it to an I/O device like a mouse is more appropriate. It gave the rat a new sense, which under the correct conditions can be manipulated to influence its behavior.
Even in that analogy, the GPU controls video processing. This part of the brain controlled reactions to stimuli and influenced decisions. You could say that it "controlled" those processes and therefore, controlled the rat in some aspects. Take one part of your brain and it does not control you, but merely a part of you, same with this scenario
@@Kayachlata, video capture card, not video card. A capture card is sensory, it isn't a GPU in the regular sense. A GPU is ancillary output processor, a capture card is used to process video (and audio) from an external source (generally for use in livestreams) without bogging down the CPU. Similarly, the human neural tissue in the rat brains was employed in sensory processing. It wasn't involved in decision making or learning, outside of processing input for use by the parts that performed those functions.
Ah so this is how Remy was born in ratatouille. They placed human neurons into the sensory area of the Rats brain, so that's why he REALLY loved food lol
This comment is golden. Maybe this is how humans evolve. Maybe we really are just the neurons and we just infect the brain of another animal and hijack their spiecies.

In case anyone was wondering this has actually been done in a human. A patient with Parkinson’s had a cell sample taken which was then cultured into dopanergic neurons. The ethics review then gave special permission for the patient to undergo experimental surgery in which these neurons were inserted into his motor cortex. The procedure appeared to lead to a halt in the progression of his Parkinson’s disease but it is hard to tell until this is being tested on a dozens of subjects

@Samir Dončić Just an undergraduate degree in bio/psychology/ neuroscience / math depending on what you want to study. Just try to go to a university where you can work in a neuroscience lab as an undergrad, thats the main thing
@Prodigious147Possible pathway is to pursue a Master's degree in Neuroscience or Neurobiology. The program will provide you with a comprehensive understanding of the brain's structure, function, and related areas of research. MSc in Biophysics can also be relevant to studying the brain and its functions, it primarily focuses on the application of physics principles to biological systems. While there may be overlapping areas between biophysics and neuroscience, a dedicated Master's degree in Neuroscience would offer a more specific and comprehensive education in the field
@@Payday5 sheesh, not only walking dead, but the crawl back to a non-rotten version resurrection. that sounds like hell. as Forbidden Siren 2 tells us: Eternal life is endless agony, no human would want to physically go through dying over and over again, even if they're effectively immortal from an age standpoint, as long as your brain remains in some way... you'd survive. also, imagine being right in your mind but your body is so rotten you can't even convey it well physically, and you can't speak, only groan. being a typical zombie but you're not mindless as they are would SUCK until breakthroughs can mentally transplant you elsewhere. also the debate of what would essentially become mass necromancy and weather or not raising the dead/rebirthing them is moral... probably not, unless y'know, you consent.
It is a modified version of the virus that infect neurons but does not cause dead of the animal because is not that virulent. Because the virus selects a specific group of cells you can trace those cells in this case the human neurons to know how much they integrated into the rat's brain. Basically, it's an overcomplicated version of a coloring book... just with genetically modified human tissue and viruses that's all.

Imagine being a rat just living your days in a cage not thinking too much about it and this dude just injects you with grief, misery, future, shame, desolation, joy, hope
Not necessarily they do think about it because if you were in a cage all day you would eventually get depressed human or not.. but it's normal because if your depressed it means your doing something wrong. It's not a disease like people claim
Right except that's not how it works. The brain transplant grew with the rat from birth. It's like they were born with it. Also, those complex emotions don't just come from a little part of our brain. Many of those are conceptual, which require a foundation of language the rat does not have.
This video is bad because it doesn't mention the study where they did exactly this, titled "Forebrain Engraftment by Human Glial Progenitor Cells Enhances Synaptic Plasticity and Learning in Adult Mice"
As the owner of a pet rat, I was so impressed at how she understood so many things, and acted in such a smart way, so quickly. I really wouldn't want her to be smarter! The kisses & love she expressed was so far ahead of most.
It's a curve where rats with satisfied needs and much encouragement embrace positivity and growth of that sort, but humans always think of more and more things to do with more and more gains, to justify taking it away from others and then shrugging off the suffering they cause as a result. Humans are pretty shitty.
It makes perfect sense that the human part of the rat's brain acted as if it was originally the rat's. The neurons have been growing with the same conditions and communications as a rat's.
I do not believe you. I believe you are an ape(homo sapiens specifically) on a computer making a joke. I do not believe you are an actual rat but I could be wrong.
It doesnt specialize in humans. It was just modified so it doesnt affect anything but human cells. Regular rabies is just as dangerous, probably more, than this.
"dollar store in vitro organoids" lol if only we could get them at the dollar store. but seriously, i'm a neuroscientist and i didn't know about these types of studies. very cool! and very well and thoroughly explained. thanks!
@@afkcnd2395 Well actually, it's important to note that the tissue *developed* normally in a *newborn* rat. While you could probably replace parts of a brain in a person old enough to have a brain disease, in the process you would be cutting out all of the connections between these neurons and the brain. Depending on the part that you are operating, this would mean cutting out either memories, particular habits or skills developed during their life, or even basic ones such as speech, sight or walking. For the most basic ones, the brain is plastic enough to adapt and reconstruct these overtime, but the older you are, the longer and harder it will be. So if you already have Alzheimer's, it's basically too late.
@@ismaeldescoings Maybe but theses limitations could be answered in may ways, for example a neuralink type device could observe or map the damaged "bit" and train the "replacement bit" to behave roughly like it, kind of like we pretrain models. Moreover we now know that we can change the phase in which cells are through epigenetics. It wouldn't be simple ok, but it's not impossible
Would be funny tho that they did the oposite meaning putting rat brain in human and then the human acted perfectly like a rat. Lol man this scientist claim they do it to help people but I think they are just being creepy.
I’d be okay running a social experiment with a group of normal rats and a group of humanoid rats. It would be interesting to see what would happen… for science of course.
The rats with human brains would enslave the normal rats and force them to start building step pyramids. Then the entire study is classified and all scientists suddenly die in accidents.

I don't know how much time it took you, but if this effort went into literature reviews of other areas it would exponentially increase both public reach and onboarding/motivating undergrads.

Not really mostly the same or very similar compounds, lookalike compounds are known as poison as the brain or budy will use them incorrectly, which is why people sometimes get very sick or worst when eating or drinking the wrong plants whether by accident or not.
@@leagueaddict8357hile the brain uses mostly the same chemicals all over they have different jobs. The chemicals themselves don't do anything, it's the receptors response to that chemical that makes a reaction. So when taking drugs for example it's not that the compounds looks similar to one in the brain (which is the case most the time) It's just how well it fits into that receptor in different parts of the brain and more importantly if it can pass the blood brain barrier
I think that they could do that because the chemical signals are very similars, those hormones should have been developed way back in the evolutionary scale and didn't change much.
I’ve had many pet rats over the years and I can tell you that I don’t doubt they are self aware without any medical intervention. I’ve watched them display having a sense of self. I’ve noticed this through watching them play into “oh hey, I know I’m cute so I don’t have to work as hard as my brother for treats”, or “damn I’m getting fat and the humans are calling me fat, time to work out and lose weight”. One of my rats absolutely understood that we were calling him fat and he took it upon himself to run on his wheel to lose weight. He even turned down treats and ate a bit less of his healthy food than he used to. A few months later and he was actually in pretty good shape and had a lot more energy. Rats aren’t stupid creatures. I’ve seen rats unscrew jars to get to snacks, open sliding cupboard doors to get into where I kept the snacks, work as a team to try and pull the meal worm box up the side of the cage. They’re very clever little animals and it’s part of why I adore them honestly. I’m not against research like this. I think it’s fascinating and the rats appear to be unharmed. I just think that people need to know that rats probably are self aware.
I don't think it's to be self aware. If anything it's pattern learning, if you called them fat and gave no treats to then makes them run on the wheel (somehow) then they'd understand that they have to run on the wheel to get a treat
@@123youbia No, you misunderstand, I didn't incentivise them to run on the wheel with treats. I didn't change my behaviour at all and they started turning down treats in favour of their healthier food. It was their own choice.
I am a medical doctor myself and I feel very sorry for the torture these poor sociable animal have to undergo. Experiments on animals rarely led to something good.
Eh, 20 billion rats are killed by domestic cats each year. If we really care about rats, we should ban outdoor felines much before we stop a helpful component of neuroscience research. It's worth it, is what I am trying to say.

@@dltr4730 I don't think physically expanding a skull is possible. Okay well. In babies it may technically be possible, because the skull is not fully fused yet...
@@DogDogGodFogyes, but that’s a human specific thing, humans are born with unfused skull plates so that they can fit through the narrower birth canals of their mothers. This is not the case with other mammals.
Don’t think so, sadly. Intelligence usually isn’t completely related to brain size or even body/brain ratio, but more by a combination of several factors, particularly by the average time it takes for parts of the brain to communicate (the time that it takes, on average, for a signal to travel from one neuron to the other in the brain, or sort of the neural density). This is why elephants aren’t as intelligent as humans, despite having much larger brains. Their physically larger brains are optimized to handle the massive amount of input from their huge body, and to control that body to keep it running and moving, but the large total neuron count required to do that makes the brain too large to perform a lot of higher-level processing. Think of it as: human brain is akin to a top-of-the-line gaming PC, while a larger brain (like an elephant’s) is like a big server in a server farm. The server might have more total power than the gaming PC, but they’re not comparable because the gaming PC is more optimized for performing singular, complex tasks while the server is meant to process massive amounts of relatively simple tasks. Or at least, that’s how it is as far as I know.
@@Tea_N_Crumpets well the correlation is 0.3 to 0.4. I totally think that increasing the brain of a person would mean higher intelligence. Bigger animals obviously need more brain mass overall. Well you also have to consider that human brains are much more complex. I mean i get it, woman and man have about the same intelligence despite man having much bigger brains but guys are also bigger on averrage. There is of obviously a lot of other factors but I'd say that you have higher intelligence if your brain is bigger if everything else is equall. You would for instance be more inteligent than your twin if extend your brain and your twin didn't. Well that all hinges on similar performance of the implant and your main brain but I think it could work in the future. There is also the issue that brain development takes decades... :,D I think it could work though. but I would never subject myself to that till it is probably tested. I definitely think this is more promising than neuralink.

So, what evidence do you have for the belief that animals are self-aware?
@@danielboone8256 well they are aware in the sense that, they react to the environment and are able to learn, It's difficult to say how aware they are
They need to put the human cells into the communication part of the brain and see what happens. In fact, due it to multiples and maybe they will start to communicate in more advanced ways. I should say I find this research highly intriguing as well as disturbing.
Yeah, i wonder if they could put the human cells on both brain modules, cerebellum and the celebral cortex. So, the rat brain is ingrown with human neurons from every side. And how that would affect their choice making and adaptability
My guess is that it wouldn't affect their communication in any significant way. Human brain cells aren't any more "advanced" than rat brain fells, it's just that more of our brain is dedicated to communication. to get more advanced communication between rats, we would need to somehow promote growth in that specific portion of their brain. But also, I feel like it would have a similar end result as Planet of the Apes
I have a dumb question, would that additional in vivo brain matter in rats boost in any form their cognitive performance? As in improved learning or spatial skills or any other form of improved performance?
I'm no actual neurologist or anything but I'd guess not really, They just wanna make use of the vaso-system provided by the mous' body. I guess for it to enhance cognitive ability it has to get organized first, in a way.
It's possible, but they didn't find any evidence of it in that study. (Starting around 7:21 in the video, the researchers looked for effects on exploration, fear learning, and object recognition, but didn't find any effects.) If they keep exploring all of the ways you can combine human and rat brain tissue, they're bound to see some effects soon, whether they happen on purpose or as a side-effect.
@@ihmcurious They should try growing full on Broca’s areas and all the other talky parts of the brain (despite appearances, I am not a neurologist) and teach the rats about language so they can do Ratatouille
This is something out pf a horror movie. Imagine having a piece of brain that doesn't belong in your head and then it starts GROWING in your actual brain until it starts to change how you behave. This feels scarier than a parasite controlling you because it's harder to notice and it feels more.. malicious. Like it feels like the brain itself is choosing to take over consciously even though it obviously isn't
Since the Brain isn't itself sentient and grows with the animal, it pretty much becomes part of that creature. If however you have a sentient brain that is more complex enough to do decision making and can overtake its host brain then yes that could be potentially malicious. Although in order for that to work said brain needs to already be adapted to its host or at least biologically be able to live in a environment similar to its host brain.

By "the two" I mean the thought coming by itself "deterministically" and the human having the thought out of their own will.
@@TechnoMinarchist I actually designed a thought experiment (considering the current technological situation anyway) for this. A human is linked up to a machine, which can correctly predict their behavior in the next seconds based on current neuron activities and outside stimulation. Every time the human is predicted to raise their foot they will earn a sugar cube while raising their foot. From the perspective of the human, this looks like they are deciding to earn sugar cubes by raising their foot and they will use this opportunity whenever needed. The sugar cube machine has become like a prosthetic extension of their body. They would sense it as just another part of their body, controlled with the same ease of will. But in reality, the machine is always ready to dispense the cube seconds before the human has the conscious will to get it. From the subjective experience of the person, it cannot be distinguished, wether they can influence the past state of the machine (and space around them) in order to achieved their present will or not. Subjective experience is real, sadly I can only proove this to myself and hope that your chemistry simulates the response an object with subjective experience would give.
Of course this can also be interpreted as "the human didn't actually think themselves" but this only objectively works for an outsiders view, where all they see is a pile of chemical reactions. Another more physically achievable thought experiment is "what would happen if a being could directly read and influence their own neurons"

The procedure appeared to lead to a halt in the progression of his Parkinson’s disease but it is hard to tell until this is being tested on a dozens of subjects

It means that brain deseases could be cured simply by replacing damaged "parts" with fresh brain cells
Weird
@@afkcnd2395 Well actually, it's important to note that the tissue *developed* normally in a *newborn* rat. While you could probably replace parts of a brain in a person old enough to have a brain disease, in the process you would be cutting out all of the connections between these neurons and the brain.
Depending on the part that you are operating, this would mean cutting out either memories, particular habits or skills developed during their life, or even basic ones such as speech, sight or walking. For the most basic ones, the brain is plastic enough to adapt and reconstruct these overtime, but the older you are, the longer and harder it will be. So if you already have Alzheimer's, it's basically too late.
@@ismaeldescoings Maybe but theses limitations could be answered in may ways, for example a neuralink type device could observe or map the damaged "bit" and train the "replacement bit" to behave roughly like it, kind of like we pretrain models.
Moreover we now know that we can change the phase in which cells are through epigenetics.

I’ve had many pet rats over the years and I can tell you that I don’t doubt they are self aware without any medical intervention. I’ve watched them display having a sense of self. I’ve noticed this through watching them play into “oh hey, I know I’m cute so I don’t have to work as hard as my brother for treats”, or “damn I’m getting fat and the humans are calling me fat, time to work out and lose weight”.
One of my rats absolutely understood that we were calling him fat and he took it upon himself to run on his wheel to lose weight. He even turned down treats and ate a bit less of his healthy food than he used to. A few months later and he was actually in pretty good shape and had a lot more energy.
Rats aren’t stupid creatures. I’ve seen rats unscrew jars to get to snacks, open sliding cupboard doors to get into where I kept the snacks, work as a team to try and pull the meal worm box up the side of the cage. They’re very clever little animals and it’s part of why I adore them honestly.
I’m not against research like this. I think it’s fascinating and the rats appear to be unharmed. I just think that people need to know that rats probably are self aware.
I don't think it's to be self aware.
If anything it's pattern learning, if you called them fat and gave no treats to then makes them run on the wheel (somehow) then they'd understand that they have to run on the wheel to get a treat

Big brain time
Bro getting a new cpu
Don’t think so, sadly. Intelligence usually isn’t completely related to brain size or even body/brain ratio, but more by a combination of several factors, particularly by the average time it takes for parts of the brain to communicate (the time that it takes, on average, for a signal to travel from one neuron to the other in the brain, or sort of the neural density). This is why elephants aren’t as intelligent as humans, despite having much larger brains. Their physically larger brains are optimized to handle the massive amount of input from their huge body, and to control that body to keep it running and moving, but the large total neuron count required to do that makes the brain too large to perform a lot of higher-level processing.
Think of it as: human brain is akin to a top-of-the-line gaming PC, while a larger brain (like an elephant’s) is like a big server in a server farm. The server might have more total power than the gaming PC, but they’re not comparable because the gaming PC is more optimized for performing singular, complex tasks while the server is meant to process massive amounts of relatively simple tasks.
Or at least, that’s how it is as far as I know.
@@Tea_N_Crumpets well the correlation is 0.3 to 0.4. I totally think that increasing the brain of a person would mean higher intelligence. Bigger animals obviously need more brain mass overall. Well you also have to consider that human brains are much more complex. I mean i get it, woman and man have about the same intelligence despite man having much bigger brains but guys are also bigger on averrage. There is of obviously a lot of other factors but I'd say that you have higher intelligence if your brain is bigger if everything else is equall. You would for instance be more inteligent than your twin if extend your brain and your twin didn't. Well that all hinges on similar performance of the implant and your main brain but I think it could work in the future. There is also the issue that brain development takes decades... :,D

Yeah, i wonder if they could put the human cells on both brain modules, cerebellum and the celebral cortex. So, the rat brain is ingrown with human neurons from every side. And how that would affect their choice making and adaptability
My guess is that it wouldn't affect their communication in any significant way. Human brain cells aren't any more "advanced" than rat brain fells, it's just that more of our brain is dedicated to communication. to get more advanced communication between rats, we would need to somehow promote growth in that specific portion of their brain.

I'm no actual neurologist or anything but I'd guess not really, They just wanna make use of the vaso-system provided by the mous' body. I guess for it to enhance cognitive ability it has to get organized first, in a way.
It's possible, but they didn't find any evidence of it in that study. (Starting around 7:21 in the video, the researchers looked for effects on exploration, fear learning, and object recognition, but didn't find any effects.) If they keep exploring all of the ways you can combine human and rat brain tissue, they're bound to see some effects soon, whether they happen on purpose or as a side-effect.

@@justbaggish I dont really know what you mean by showing myself , but I can say that I try to express my dream and my feelings . It's fun :))
@@showyourself9796 I think it's cool and all. Just made the joke to make you laugh.
@@justbaggish It's ok . It was fun xD Maybe I was overthinking a bit
They were so preoccupied with whether or not they could they never stopped to consider whether they should.
They always should, cowardice holds back innovation
@@mjbaricua7403and innovation can sometimes be bad, (not always tho)
And they should, Decels are the bane of existence.
I just found your channel. New sub! I really enjoyed your manner of communicating fringe science in an informative and engaging way.
the last part: what if rats develop conciousnes?
me: ah yes the equivalent of "it's all fun and games until we find out we're the rats and alines are the researchers"
You know when the rat brain is overtaken by human brain cells when they start to declare wars and are deeply interested in money and shiny objects.
Skavens
Nah that only happens when they're put into a perfect (dys)utopian society made to answer all their needs until they eventually collapse onto each other and go insane.
You just described Israel
@@justanotherguyful _"You know when humans have overtaken Israel, when they start to declare wars and are deeply interested in money and shiny objects."_
Yeah, the cancer is everywhere. No need to mention any specific country.
@@justanotherguyful no they just described humanity in general.
Ugh. Thats fucking horrifying. I can't even imagine the mental shenanigans that would ensue.
We need to use this method control rats into spinning horizontally when Free Bird is playing.
7:07 To me it seems a lot more like the rat learning using that new human brain matter as a sense. So yeah I guess the Pavlov’s dog thing still makes sense
I would call the sense "sibseria"
I'm ready for a science fiction story in which dolphin brain tissue is implanted in human embryos.
Horror story
@@Wyi-the-rogue Yes, you're right. That's the genre I speak. Do we get our popcorn out, or do we run for the hills? (Sorry, in a Saturday night thriller mood.)
Dolphins 🐬 along with the rest of Cetacea don't seem to dream, at least in noticeable amounts with REM sleep.
Plus, you could end up with a human body dog 🐕, which would be pretty cute given dogs' cute personality.
eee ee e eee e
@@snkybrki Took me a second to get that. 😄
It's begun. Pinky and the Brain is no longer just a cartoon...
Can't wait for the tabloids to get hold of this.
...or Christian radio. They haven't even gotten over evolution
This will probably be the silliest comment on this page, but I used to think this was how Yo-yo's worked as a kid. When I heard a kid had a yo-yo with, "10 brains" I thought they somehow created robotic brain networks and implanted 10 of them in the toy so that it could respond better to the kid's maneuvers. When I found out that the brains were just metal balls, my world was shattered. Anyway, I cant wait to see what kind of technology is birthed from this.
Master Splinter, Lezz Goo !!! 🔥🔥🔥
Fantastic video 😃
This reminds me of the book Flowers for Algernon, where they experiment on two patients with down syndrome. One mouse, one human. The experiment works, both subjects display remarkable gains in intelligence, to the point that they are smarter than the average of their species. Unfortunately the therapy it stops working, and we get to read of the mental decline of the human patient. The mouse ends up dying as a result of rapid intellectual decline, it stops eating as a result of depression. The human contemplates suicide as well. Really fucking sad.
Exactly what I thought when I saw the video's name and thumbnail
love all these ppl being scared/disturbed, isn't this just fascinating?
If they fuck up would humanity want a war with self aware rats?
crazy to imagine the fact that we have the ability to just... *think* ... i dont know how to explain, just simply *thinking* is possible all thanks to these little tiny electrocuted strings forming together
Wait until you realise that it's not you that does the thinking. The thinking simply happens, simply occurs, without your willing it to.
A thought comes when _it_ wants, not when we want.
@@TechnoMinarchist Yeah, especially while writing tests. The thought really likes coming when it wants, huh. :p
@@TechnoMinarchistFor a human it is impossible to distinguish between the two. Insisting on any side is unprovable and undisprovable, thus of no use outside the philosophy of "but what if?".
By "the two" I mean the thought coming by itself "deterministically" and the human having the thought out of their own will.
@@TechnoMinarchist
I actually designed a thought experiment (considering the current technological situation anyway) for this.
A human is linked up to a machine, which can correctly predict their behavior in the next seconds based on current neuron activities and outside stimulation.
Every time the human is predicted to raise their foot they will earn a sugar cube while raising their foot.
From the perspective of the human, this looks like they are deciding to earn sugar cubes by raising their foot and they will use this opportunity whenever needed. The sugar cube machine has become like a prosthetic extension of their body. They would sense it as just another part of their body, controlled with the same ease of will.
But in reality, the machine is always ready to dispense the cube seconds before the human has the conscious will to get it.
From the subjective experience of the person, it cannot be distinguished, wether they can influence the past state of the machine (and space around them) in order to achieved their present will or not. Subjective experience is real, sadly I can only proove this to myself and hope that your chemistry simulates the response an object with subjective experience would give.
Of course this can also be interpreted as "the human didn't actually think themselves" but this only objectively works for an outsiders view, where all they see is a pile of chemical reactions.
Another more physically achievable thought experiment is "what would happen if a being could directly read and influence their own neurons"
It's crazy because this video came out a year ago but I was learning about this in my university neurobiology class almost a decade ago...
Optogenetics and epigenetics are two of the most fascinating things I've ever learned about
It's Pinky, Pinky and the Brain, Brain, Brain, Brain, Brain.
as a synthetic virologist..i can safely say, this is ethically on thin ice....but that wont stop a Ph. D. canidate!!😮
Kettle calls pot a water filled fool. How bout that.
@@anonymous-fm2bg manipulating amino acids is a very distant far cry from CHIMERA ASSEMBLY.......read a book
The fact that they're attempting this means they've run out of real scientific breakthroughs to chase
We probably have done math wrong if we can't find new breakthroughs in science tbh
Science isn't made of breakthroughs it's built upon like adding bricks to a castle. Only in extraordinary cases do you see a wall torn down and a new one erected in its place.
the fuck are you on. We've made breakthroughs faster than ever, nearly one or more every month. Besides they would attempt this eitherway, breathroughs arent a factor. Scientific experiments aren't motivated through breathroughs. They're motivated through possible breakthroughs. And theres a lot of possible breakthroughs that could happen
I remember headlines like 20 years ago like "Scientists Put Human Brain Cells In Lab Animals" and Fox News yelling about it for like three days at one point but I always wondered what was really going on with that and now I know!
What do those morons not scream about? This stuff is going to help hundreds of thousands of children and adults with debilitating diseases that otherwise would entail a lifetime of suffering.
But no, my sky daddy didnt approve this or what do the rat feel?
Oh yeah. Totally wont be used for anything dubious in 50 years. 😵💫
No, the United States of America is not currently developing self-replicating biomechanical killer drones
Probably already is.
@@trajectoryunown considering we cant even handle production for conventional weapons out of wartime + incompetency, im 99% sure it is not currently being worked on
If this interests you at all especially in a deeply unnerving way you should look into a book called blood music. Essentially, they're doing something very similar to this single book and they end up making a conscious disease that can think like us.
Good thing matter can’t produce self-aware consciousness then.
hmm, yes, the in-vitro organoids which are available at every dollar store. i've definitely upgraded to the in-vivo model and it's made all the difference.
So you're telling me, the first animal I'll ever be able to have an actual conversation with.. is gonna be a rat.
*Not complaining.*
You heard of parrots?
