this is fascinating, and I thank you for your time in it, even if you dipped out of it in the end.

Question, if you've got the bandwidth - I've got a cochlear implant which feels like it's at least a little tangential in terms of hooking into the electrodes and auditory nerves ... been wearing this wonderful thing for 30 years, and I'm curious as to why the body would reject his implant versus mine (and other folks who wear CI's)?

I couldn't tell you why the CI is accepted long-term, but the penetrating electrode arrays like the one in the article actually puncture the surface of the brain with tiny needles and cause the surrounding tissue to scar/calcify.

There are non-penetrating arrays that sit just above the brain (avoiding this problem to a large degree), but they don't have anywhere near the precision of the penetrating sensors.

Will Neuralink have the same problem? Seems like that would put a big damper on the insane level of hype around it.
