I think that Facebook with their acquisition of Ctrl labs are further ahead than most people think I’in HCI and might even be ahead of neurallink, especially as Facebook has significantly more money behind their effort.
Yeah CTRL labs has been flying under the radar, but they have a ton of top talent and already demonstrated insane results. I will go further to say they are easily ahead of neuralink in terms of bringing a faster-bandwidth interface; of course, for more ambitious projects that Musk has tweeted about like mental health disorders, you must go through the brain, but there's no indication the neuralink approach will scale to this either.
