Neuralink just streamed a short video with their first human patient playing chess and controlling his MacBook with his brain only: https://x.com/neuralink/status/1770563939413496146

Of course we are in the very early days of this particular branch of humanity's tech tree, but I can't wait to see where this is going!

At university, I took a class on "brain computer interface". In the first lecture, the professor showed a short video of a monkey with a chip implanted. He pointed out that invasive BCIs are much more precise, but infeasible for humans. Then we spent the semester dealing with noise filtering for non-invasive human BCI.
