>>12060606pic related is probably the only real thing that will come out of neuralink, along with other analogous functions like restoring sensation, restoring vision, hearing or removing pain, note how connecting the motor neurons together are almost a trivial task, the main thing holding us back there is just the technology, whereas what is holding us back in analysing higher brain function is the actual neurobiology of higher brain functions
almost certainly we will not get to the level where you are uploading your brain or downloading anything into your brain or doing telepathy or whatever other dumbass scifi shit musk is promoting, before we somehow obtain a way to in vivo measure the activity of individual neurons in a brain.
