Neuralink seems really interesting but so far I haven't seen any evidence that they've made any progress on the scar tissue problem that puts a limit on the practicality of these kinds of implants. If anyone here has more knowledge about this issue and whether there is progress being made, I'd love to hear it.

it's pretty goddamn invasive anon.

>>minimally invasive procedures
that's still surgery. Even minimally invasive surgery is expensive. The fact that minimally invasive brain surgery can't be done by a dude who never finished high school in a mall is what makes it expensive. If you want fucking FDVR you might need to do some very very very invasive surgery, like chopping up the spinal cord and putting a chip in between. If we can make automated robot surgeons this may help.

solved. We have monkeys that are going on 7+ years with neural interfaces in their heads. The bandwidth of the interfaces they have needs to improve though. The surgery they have to do to implant them is rather intense. The neural sewing machine will fix that. But it still requires surgery.

FUCK NO! They predate peak graphene hype. It's microwire arrays. This is similar to what the neural sewing machine neuralink made implants...

>>10581895
ok fine. I use it for typing fast, especially with GNU emacs. We haven't had high bandwidth neural interfaces before, so we're really not sure what's possible
>>10581903
there are some indications that we can prevent this

What do you think a neural interface is numbskull?

Yiff in hell furfag!

Spoiler alert: it's a machine that lasers holes in your brain and then puts tiny electrodes in them with a needle once per second:

>> is it just a pop sci-fi daydream?
currently it is. We don't have a good way to make stable neural interfaces. If you can't control limbs, there's no point in ripping them off and bolting new ones on.
>> Are we progressing this technology fast enough where this could be an issue before the close of the century?
hopefully. Biology is hard and we do not understand it all that well. Making neural interfaces is going to require a great deal of science, engineering, and medicine to realize. Just making good limbs is difficult to. There's connecting limbs to the body, which might get weird when parts have to go through/connect to skin. Connecting stiff metal part to soft jelly is a hard problem. The metal part tends to rip out(OUCH!). By mass, our actuators aren't as strong as muscle.
>>I was thinking about what controversy would result if they ended up becoming better than they were before
that's been done to death. There's the possibility that becoming better might come at a cost. For example, one scenario presented in deus ex is that you have to keep taking a drug for the rest of your life otherwise your body rejects the implants. That could actually happen. Artificial limbs can't self heal so break down could be an issue, and maintenance will certainly be necessary. There's also the risk that because some of these operations are irreversible, so once better tech comes out you might be stuck with it.

this came out recently:

LOOK AT THE PICTURE. SEE the SKULL, the part of bone removed, the flexible microwire electrode array, the laser ablating microdurotomy cauterizing brain drill, the targeting camera stack, the microwire needle implanter. THE LATEST NEW NEURAL SEWING TO CONTAIN ALL THESE MICROWIRE ELECTRODES!!! EVEN IN THE THIN SKULLS OF LABORATORY RHESUS MACAQUES.
