So we can do this with functioning brain cells but we can't have abortions? Seems a bit.. fucked

[–] NewSocialWhoDis@lemmy.zip 10 points 1 day ago (2 children)

Ok ok, hear me out, what if they were harvested neurons from someone everyone wishes had gotten punished for their crimes, but never was? Hitler or Stalin? Or Trump! Or Putin!

[–] SLVRDRGN@lemmy.world 2 points 1 day ago (2 children)

Trump is still alive - he can and should be punished for his crimes. I don't know what makes him special that he should never be.

[–] Xella@lemmy.world 1 points 9 hours ago

Of course he should be, but will he be? It's not up to us plebs to decide whether he is punished or not unfortunately.

[–] NewSocialWhoDis@lemmy.zip 2 points 23 hours ago

Whoa whoa whoa. I said will never be punished, not should never be punished.

And Trump and Putin are both still alive.

Love this idea. This new form of consciousness is terrifying but your ideas makes it more tolerable for me. ❤️

[–] KernelTale@programming.dev 3 points 1 day ago

It actually makes me even more concerned. I don't want dead monsters to suffer. I want them to be dead.

[–] Clbull@lemmy.world 41 points 1 day ago* (last edited 1 day ago) (4 children)

Cortical Labs are the ones who pulled this off. They already have biological computers running on 800,000 lab-grown neurons available for ~$35,000 (just going on what a quick Google search told me) and are planning to open up a cloud computing service with its own API soon.

This makes me feel uneasy. Imagine if reincarnation were a thing and you get brought back into this world, and your purpose is to learn how to play DOOM.

[–] Sarothazrom@lemmy.world 7 points 1 day ago

aw sweet, man made horrors beyond my comprehension 😍

[–] gerryflap@feddit.nl 23 points 1 day ago (5 children)

Personally my worry really isn't reincarnation, there's no reason to believe that that's true. But if these are fundamentally the same neurons that make up our brains, then how much do you need to put together before they acquire some form of "sentience"? Does a clump of 800,000 human neurons experience pain, sadness, a sense of self? Where is the line between an emotionless biocomputer and torturing a living organism for its entire lifespan?

Despite the fact that I really hate "AI", that question was of course already sort of relevant for the latest AI models, even though we can generally conclude that they're not there yet at all. But real neurons are different, we know what they're capable of. How many do you need before a clump of neurons has rights?

[–] Jyek@sh.itjust.works 11 points 1 day ago (2 children)

Large language models are not intelligent. They are predictive text applications with massive dictionaries of circumstantial sentence structures to choose from. Nothing more. They do not feel and do not think for themselves. The only time they do anything is when the API calls them to produce more text with an updated context string.

There's another bunch of guys who are trying to do the same thing with rat neurons on the cheap using Gatorade as a growth medium.

OK but hear me out here, I think I have the beginnings of a business plan:

  1. Create the Torment Nexus

  2. ?

  3. Profit

Some components of the plan are still under development, but let's not lose momentum. We can advance with the initial phase while brainstorming to refine the plan in real time as we progress. It's an exciting opportunity and we mustn't forfeit our first-to-market advantage.

Iirc the study found that the neurons played "slightly better than buttons being pressed at random" or something like that, so it's hardly pro gamer brain chip.

I have no mouth and I must Doom.

[–] Sturgist@lemmy.ca 17 points 1 day ago

Honestly? Sounds preferable to being stuck in the universe of I Have No Mouth And I Must Scream..... I'll take a challenging power fantasy with some massively overpowered weapons over millennia of endless physical and psychological torture by an insane AI..... might just be me though...

Taking "will it run doom" one step too far.

[–] tpihkal@lemmy.world 72 points 2 days ago (4 children)

We need to take it back a step and see if it'll run Linux.

Asking someone to compile the kernel with their mind sure is one way to give someone a headache

Next step: putting the cells into one of those Boston Dynamics robot dogs with a gun attached. What could go wrong?

Raises uncomfortable questions about consciousness. The only difference between these neurons and your own are the number of them and the structures they form. Of course it doesn't know what it's doing, but... Neither do our own neurons

Am I the only one who wonders why, in a world where there are already concerns about machines rebellion, when we train rats, robots and a bench of neurons to play a game, it HAS to be Doom, we can't think about another, non-violent, or let's be bold: non-destructive game??

[–] UnderpantsWeevil@lemmy.world 19 points 1 day ago (3 children)

They trained a tiny patch of neurons to respond to low-voltage electric impulses. The cells don't know they're playing Doom. They don't have any kind of social context or even video feedback.

Imagine if I stuck you in a sensory deprivation chamber, handed you an NES controller, and asked you to hit the buttons. Then, periodically, I said "Yes" or "No" based on the buttons you pressed. And when I pulled you out of the tube at the end of an hour, I told you "the yes and no messages were intended to encourage you to correctly navigate Mario through the first level of the original game." What if, instead of Mario, I'd been telling you how to play Street Fighter?

It doesn't matter if its Doom. They likely picked Doom because the I/O is so rudimentary that you can install the game on practically anything. The cellular matter has no idea what it's doing beyond the "Yes/No" signaling.

[–] jaggedrobotpubes@lemmy.world 2 points 1 day ago

Tetris.

Pong.

So, uh... is it any good at it?

[–] AEsheron@lemmy.world 10 points 1 day ago (2 children)

IIRC, it doesn't actually pay the game itself. We prod the cells, they fire in a certain way and that response is read to convert it to an output for the game. The cells aren't a rudimentary Doom bot, they're the controller.

Having worked with human neurons harvested from dead people, there are worse ways to extend your life. At least these ones get to play games instead of getting poked and zapped by me.

we grew a human brain

200'000 ~~brian~~ "brain cells" (so about 1/3 of it neurons) is the equivalent to a really simple microcontroller.

Edit: left the typo for funny

[–] ameancow@lemmy.world 3 points 1 day ago* (last edited 1 day ago)

Yah but the visuals of "growing a human brain and trapping it in hell" gets a lot more clicks than "We made a very basic microcontroller out of organic chemistry to interact with an old video game poorly."

[–] SabinStargem@lemmy.today 2 points 1 day ago

As it turns out, Doomguy is a robot clone of BJ Blazkowitz, who was deliberately smuggled onto Mars by scientists who knew about Hell.

[–] HailHydra@infosec.pub 73 points 2 days ago* (last edited 2 days ago) (5 children)

I'm not sure if it's the same scientists, but the YouTube channel The Thought Emporium has an ongoing series about growing neurons to play retro games (such as OG DOOM).

The playlist of this series is fittingly called Building the Torment Nexus.
