For those who don’t know much about this field, this seems incredible. The reality is that this a tech demo that Neuralink is using to practice the basics. For other research groups in this field, this is tech from 20 years ago. The current state of the art is humans, mostly quadriplegic people, with chips which let them control robot arms with enough accuracy to pick up small delicate objects, play games, and type b…

Would it be possible to control an extra arm somehow? Or brain plasticity doesn't go that far?

I don't understand how you can gather such a targeted signal by sticking wires in just a few places. Like, you can't just tape a metal coat hanger to an iPhone and start getting text messages through it. But somehow you can put some wires just as few mm into the surface of a brain and extract fine motor signals??

The most interesting thing here is not the mind reading, it is the miniaturization of computing and sparse data transfer. Neuralink off-loaded the computation to the sensor, sending back aggregate data snapshots. Usually you will need massive ASIC/FPGA computation banks with a lot of messy to handle the data transfer and readout but they took a shortcut bye sending only counts of spikes that exceeds a certain thresho…

This particular exercise could've been done with EEG. Where Neuralink excels is in having a much higher possible bitrate. Pong is the absolute POC. Neuralink will most likely be able to achieve higher differentiability and thus be able to complete tasks of higher complexity, so stay tuned for even more impressive tasks. EEG can't get past pong; it's limited by physics itself. The solution is to put the electrodes in…

The brain is very plastic, it probably would adapt at any consistent input. A most interesting question is, what would you sacrifice? Because the part that you would use to control your extra tentacle or whatever is probably currently used for something. If you are missing an arm is obvious what part of your brain you would use, otherwise, some sacrifice probably have to happen. Even reading, it seems, take the space…

Our brain interface tech is so primitive, but it holds incredible promise if we're able to solve it. Imagine being able to virtualize consciousness, back up memories, live forever... The problem is how invasive it is, and how little reward there is initially. We have to solve the chicken and egg problem, but unfortunately cracking open the skull and sticking electrodes into the brain is not something one typically wa…

Digitizing consciousness is a much harder problem, because we don't really understand how much of the brain works, the areas involved with conscious thought in particular, and the exact learning mechanisms the brain employs. The way we do deep learning these days is a very rough approximation of how the brain might work, and backpropagation is not really biologically plausible. So IMO, digitized consciousness is prob…
