What& #39;s cooler than (an awesome! wireless demo plus) promising *hypothetical* automated through-skull surgery to implant a BCI? Actual minimally-invasive surgery in humans to implant a BCI:

Also under-appreciated: functional ultrasound. They can do this through a baby& #39;s (very thin & soft) skull. So you could perhaps just thin the skull of an adult and do this through a thin layer of skull without ever touching the brain itself = much safer. https://erc.europa.eu/projects-figures/stories/babys-brain-never-seen">https://erc.europa.eu/projects-...

It doesn& #39;t meet the exact design constraints Neuralink is using. But the question is whether those are the right design constraints to be using. With enough engineering this kind of thing could be extremely powerful and safe as a BCI, I suspect.
