Another inherent problem with BCI is that it’s not seamless. It takes a lot more concentration to operate a mouse with your mind than it does with your body. People don’t really understand how much of their movement is handled by their spinal chord instead of the brain.

People have a hard time utilizing interactive spaces when we separate them from physical input. Which is why a lot of people struggle with VR,. When your physical senses like proprioception don’t reflect the interactions the same as our visual senses we can become physically ill.

I always got more the sense that musk was looking more for some sort of, mass adoption for this technology. Ghost in the shell, matrix type shit, that we're still probably like, a century away from. If we don't boil ourselves first, anyways. But that also might be marketing mumbo jumbo from him, and none of that really kind of solves any of his short term problems that he'd have, which you've done a good job pointing out, and are probably more relevant.

The toughness of figuring out use is definitely a good point, and it's one you see all over the place with all manner of disabilities. It's sort of unnatural enough to learn how to use a keyboard and mouse already, and those are relatively simple technologies, which is to say nothing of the maybe months of training it would take to learn how to use a prosthetic limb. I think maybe kids, children, could learn and pick up on stuff much faster, but I really don't think it would be a popular decision to decide to start testing your BCI on kids, even if you were to reach a state where it was benign, useful, and guaranteed to be stable.

I also think musk probably doesn't understand how BCI probably won't help much for easing human-computer interface, because it sort of, puts the onus of everything on the person, as being at fault for not being able to interface with the perfect, "flawless" machine, rather than just viewing them as another kind of being, with distinct, even somewhat hardwired limitations. Humans can't really split their attention and do dual processing, they can only focus on one thing at a time, and that strikes me as a pretty big limitation on the amount of data that you're going to be able to extract from someone with one of these interfaces, even if it was effortless to use. If you want them to be able to walk around and still be a functional person, anyways, and not be insane and schizophrenic maybe. I think we also have been saying that we can solve a lot of those processing problems much easier on the computer side with these horrible organoids that are stitched to mice and computers and stuff. So that would be pretty neat.

In any case, to me, this would all seem to be a little bit overkill, for those intentions, when you could just get everyone to learn stenotype, if you really wanted to "increase output". Which, again, I'm not sure would really work.

That's also all taking musk strictly at face value on his intentions, but I'm pretty sure the guy likes rockets and electric cars because he has a retrofuturist "I'm the great man of history" kind of deal going on, so I don't think I'd put it past him to think that having a plug that goes into your brain and puts you in the matrix would be a "cool" idea.
