The 29-year-old complete quadriplegic shared that he had lost sensation and suffered paralysis from below the shoulders after sustaining a spinal injury during a diving accident eight years ago

Arbaugh also revealed that the implant had given him the freedom to pull an all-nighter playing the strategy game Sid Meier’s Civilization 6 - something that he could not have done on his own before the surgery.

This is the kind of use case for neuralink that I'm okay with.

[-] AlolanYoda@mander.xyz 48 points 7 months ago

I'm glad they're having success, but this is not a use case for neuralink. It's a use case for brain-computer interfaces in general. Research in BCIs is ongoing and a very relevant topic of research, but usually research institutes can't indiscriminately kill monkeys for this. I am very excited about this tech (my PhD is tangentially related to it) but wish it was being developed by literally any research institute not owned by Musk

[-] Tar_alcaran@sh.itjust.works 12 points 7 months ago

I'm also pretty sure you can do this without implants...

[-] Dasus@lemmy.world 11 points 7 months ago

Yeah, you're not wrong, per se.

I might be completely stupid and wrong about this and everything, but I don't think I'm too far off.

Essentially Neuralink is just very high tier EEG, electroencephalography, measuring brainwaves.

You can buy yourself a kit for 100 bucks or so. But... you'll get like a two-channel device with a few sensors, which won't really have any sort of accuracy. You could go for a professional model for a few thousand or something, and have good sensors and a few dozen channels.

They'll still be outside the skull though.

I just looked this up the other day, and uh, guess the amount of channels on Neuralink?

"Neuralink has developed an application-specific integrated circuit to create a 1,536-channel recording system. This system consists of 256 amplifiers capable of being individually programmed, analog-to-digital converters within the chip and peripheral circuit control to serialize the digitized information obtained."

So I don't know what would be a good comparison to the scale difference here. Perhaps one is like listening to someone having sex in the next room while there's also loud music playing (limited channels, poor-ish signal), and the other is actually being in that room, having that sex yourself (100x the channels, signal pretty much straight from the source.)

Someone smarter can correct me where I went wrong.

This technology is fascinating, I'm just so annoyed/apprehensive Musk owns the company doing the pioneering work.

[-] Tar_alcaran@sh.itjust.works 3 points 7 months ago

Having a thousand, or a hundred, or a dozen channels means nothing if you can't individually control them. You can use a hundred channels to sample a brain, but if you're playing chess (As in the famous video) all you need is "up/down, left/Right, click". That's 3.

[-] Grimy@lemmy.world 10 points 7 months ago

The brain is incredibly complicated and there is a lot of noise. More channels do make a huge difference. It's not like each channel is associated to one direction or something and you only need 4. Also, to add to the other users point, the signal strength is much stronger inside than out since the skull acts like a barrier.

Your example is the equivalent of saying you don't need a keyboard because you can use a computer with just the arrow keys and the spacebar.

Although BCIs are already a thing, the difference between what you can do with external compared to internal ones is probably quite vaste at our current tech level and will probably lead to better external ones at the same time.

You also don't control the electrodes, you just receive the signal from them and they are obviously all being sampled.

[-] Dasus@lemmy.world 4 points 7 months ago

Well you'll need three states which are easily translated to the commands.

The more channels you have, the easier it is tor recognise any specific configuration of brainwaves.

It's not like thoughts are as easy to pinpoint as spatial coordinates. You don't really decide what your specific brainwave output will be when you focus on thinking "up". It will be a combination of different brain waves, and the more accurately you can measure that, the easier it is for the computer to pick up when you're thinking "up".

Try playing a tune with just three tones available to you, it'd be hard.

The technology isn't new, but the resolution sort of is.

Hell they used the tech in a House episode in like, 2009.

What do you mean "if you can't control them"? The channels are how many bands you're reading, and they are using quite fancy computers to do the reading. What's there to control? BCI is just a fancier interface than a keyboard, it's still only one-way, so I don't understand what you mean by "control" in this context.

[-] ummthatguy@lemmy.world 10 points 7 months ago

Certainly, but the tech itself throws up some flags for potential abuse.

[-] skyler@lemmy.world 4 points 7 months ago* (last edited 7 months ago)

Agreed. Plus the animal testing is bad.

I'm hopeful that the tech won't be abused because it's life changing for those that need it.

[-] julianh@lemm.ee 4 points 7 months ago

It's the tech industry, and it's Elon Musk. It will be abused. It's not a matter of if, it's just a question of what horrible way they'll misuse this for profit.

[-] captainastronaut@seattlelunarsociety.org 26 points 7 months ago

I’m happy for this guy that it seems to be helping him. But I cannot stress how much I DO NOT TRUST THIS COMPANY at all. I would be 0% surprised if we find out five years from now they killed 10 other patients and this is the only story they chose to share. I don’t believe they have any integrity and the little bit that has leaked out about their “research” practices has been horrific.

This is being reported like it is scientific communication about the research. But this is the spin machine of a for-profit company. 

[-] FlyingSquid@lemmy.world 19 points 7 months ago

I'm glad Neuralink has developed such essential technology. I can't think of a better use of a brain implant than not sleeping and playing Civilization.

[-] ummthatguy@lemmy.world 20 points 7 months ago

[-] ivanafterall@kbin.social 7 points 7 months ago

Huh.

[-] ummthatguy@lemmy.world 9 points 7 months ago

s5e6 "The Game"

Wesley Crusher returns to the Enterprise on vacation from the Academy only to discover a mysterious alien game infiltrating and controlling the crew.

[-] ivanafterall@kbin.social 8 points 7 months ago

It seems to be infiltrating her alright...

[-] ummthatguy@lemmy.world 15 points 7 months ago

I mean, it's no candle ghost, but it'll do.

[-] Semi-Hemi-Demigod@kbin.social 10 points 7 months ago

I can't criticize it because I use essential technology to do the same thing.

[-] FlyingSquid@lemmy.world 9 points 7 months ago

Did it require surgery at a cost of millions of dollars?

[-] Semi-Hemi-Demigod@kbin.social 12 points 7 months ago

No but my back hurts way more than it should

[-] FlyingSquid@lemmy.world 6 points 7 months ago

You presumably have a homo sapiens back but you aren't a hunter-gatherer. I don't know about "more than it should." I don't know that I've yet to meet someone over 40 without at least occasional back pain.

[-] humbletightband@lemmy.dbzer0.com 7 points 7 months ago

I can't think of a better use of a brain implant than not sleeping and playing Civilization.

I can come up with a few:

  1. Showing advertisement while the recipient is sleeping. Use a positive feedback loop in order to increase engagement.

  2. Using it to fly bomb carrying drones

  3. Create jobs that have only one requirement - having such an implant.

[-] FlyingSquid@lemmy.world 5 points 7 months ago

Charge $8 a month for Neuralink Plus to enable long-term memories?

[-] humbletightband@lemmy.dbzer0.com 3 points 7 months ago

Omg, that's the innovation I was looking for

[-] Grimy@lemmy.world 1 points 7 months ago

He's paralyzed from the neck down and can now use a computer like a regular person. Not sure what there is to be sarcastic about.

[-] FlyingSquid@lemmy.world 3 points 7 months ago

Welcome to Ten Forward! Are you new here?

[-] trolololol@lemmy.world 2 points 7 months ago

First time huh

[-] dumpsterlid@lemmy.world 12 points 7 months ago

I’d use the neuralink to stay up all night figuring out how to prove Tuvok wrong and make casual condescending remarks to him about my intellectually superior understanding of things.

Resistance is futile. You will be assimilated.

~ 2. Keep it civil. Disagreements will happen both on lore and preferences. That's okay! Just don't let it make you forget that the person you are talking to is also a person.

~ 3. Use spoiler tags. This applies to any episodes that have dropped within 3 months prior of your posting. After that it's free game.

~ 4. Keep it Trek related. This one is kind of a gimme but keep as on topic as possible.

~ 5. Keep posts to a limit. We all love Star Trek stuff but 3-4 posts in an hour is plenty enough.

~ 6. Try to not repost. Mistakes happen, we get it! But try to not repost anything from within the past 1-2 months.

~ 7. No General AI Art. Posts of simple AI art do not 'inspire jamaharon' and fuck over our artist friends.

Fun will now commence.
