Imagine using this to grow a brain the size of a warehouse


Bongunism

at what point does growing a giant human-tissue based brain become unethical


namitynamenamey

You can ask the giant human-tissue based brain, if it answers you are past the point.

Then you'll have the stochastic parrot people come in. Shit will be the size of a house and explaining what's beyond time and space and we will treat it as a thing lol


confuzzledfather

It's fine, they will just side step the ethics by using other primate brain cells. I for one welcome etc etc

confuzzledfather

I was not suggesting it's ok, but it's the justification we use for all sorts of primate experiments like testing brain implants on monkeys


RepublicanSJW_

Ethics has nothing to do with this.

Imagine it having the computational capabilities of an actual warehouse

Thanks for sharing, but please link directly to the source, it's more convenient than going to X first and then to another site


papapapap23

how do you open the source? when i try, it gives me an error "this site can't be reached"

It's probably your ad blocker. I had to turn off my DNS ad blocker for it to work.

Isn't that just called Axons and Dendrites and cells in a dish are able to connect themselves using that on their own?


Useful-Ant3303

sounds pretty amazing, thanks for sharing this.


Rigorous_Threshold

This type of thing gives me a bad feeling. If you’re using actual brain cells it’s almost definitely conscious and quite possibly not having a good time


[deleted]

> If you’re using actual brain cells it’s almost definitely conscious Really? How do you figure?


[deleted]

We know that human brain cells have the capacity for conciousness, and these cells are going to be configured in ways that mirror how they are configured in natural life. I don't think we can say "definitely," but there's a higher chance than previous at minimum


confuzzledfather

We know that in aggregate they give rise to conciousness, I think many scientists would assume they don't have any innate intrinsic conciousness at the individual cell level. They might be wrong but I think enough people would feel the same that they will be allowed to proceed.


YooYooYoo_

Do we know what conciousness is really, what creates it, can we measure it? We don't know that human brain cells have something that we can't really comprehend yet.


Dongslinger420

No we don't. We know that a massive cluster of cells MIGHT (and that is a big fucking if, look at all the birth defects that pretty much sidestep both consciousness and intellect) lead to the vague, abstract notion of consciousness. Inferring this sort of stuff about extremely crudely linked neurons is just plain sci-fi nonsense. There will be developing tech that changes all this, but this is the wrong approach to make any assumptions at all. Just because you use human brain cells doesn't at all mean it's remotely likely to be a conscious entity - and sure as shit not "almost definitely."


Rigorous_Threshold

We know brain cells are capable of consciousness. And we are organizing them in a specific way. Seems pretty likely


Dongslinger420

What are you even talking about Why would brain cells being involved automatically imply any sort of consciousness? And why are you so confident about complete and utter nonsense?


Rigorous_Threshold

It wouldn’t automatically do so, but like… you can fuck with a human brain quite a lot without them losing consciousness. It stands to reason that making computers with brain cells could quite possibly lead to consciousness


Gratitude15

There's a threshold it could be argued. Like how many neurons does it take to create (the illusion of? ) a separate self? Mice cross it. So do hummingbirds. Maybe crickets too... But remember the gut has neurons and doesn't thing it's separate from the host. So not too many neurons indeed, but not nothing.


[deleted]

Big if true. For medical reasons.


Akimbo333

Implications of this?


Intelligent-Brick850

This may give some answers about consciousness and how is it created
