#2Very cool. The opportunity for people with physical impairments to continue communicating - and convey their ability to still experience the world - gives us the ability to help these people lead happier lives.

#3It wouldn't be particularly hard for a trained person to block their thoughts to a brain implant, if the police were trying to read their mind.

If the police are able to implant a device into your brain to get information out of you, I think you're screwed either way as the good 'ol rubber hose method is likely on the table - at least until people commonly elect to do the surgery or the surgery somehow gets to legendary levels of safety in the dystopian future.

#5The next truly massive tech revolution will have to be something even we tech peeps reject. And I think bodily embedded stuff would do the trick.
It could be amazingly effective though if this is where we’re at already. Imagine the speed and enjoyment increase for anything from typing to gaming to driving a car. You’d get completely left behind if you rejected it.

#6Interesting that the imagined letters are single-stroke, with no pen lifting, somewhat like most of the PalmOS graffiti letter forms.

It wouldn't be any different from trying to force a confession through torture. You need to control your thoughts during the interrogation.

Don't get me wrong I'm sure there will be advances. But this current tech is based off reading nerve data meant to be movement data - the user needs to mentally trace each letter.
So I don't see this form of the tech at least being able to compete with qwerty let alone stenography.
Actually to that point, stenography would allow people to input data (it must be language specific and error tolerant but most BCI is as well) at ~5x the average typing speed on qwerty but that hasn't proliferated.
EDIT: On second thought I could see it matching physical movement, maybe _slightly_ outperforming it by a few % by skipping a few physical limitations. I think this should be essentially identical to any other physical motion based communication.

Oh that's interesting, make them think the thoughts at least for extraction. This first version of the tech requires the user to mentally imagine moving muscles to trace letters so yeah it's not likely to be an option... yet.
I wonder what happens to these BCI results when the user is on psychedelics a la MK Ultra
EDIT: Wait your point was slightly different then I first read but that makes perfect sense!

I'd be interested in knowing how this metric changes over time as the user gains more experience with the BCI device. The article mentions that researchers recorded his neural activity while he was thinking about writing letters. Would the man eventually find that the system is more accurate or faster when he instead learns how to think "the thought that generates the letter A in my BCI device"? Fascinating stuff all around.
