We've been able to get a one- or two-dimensional control signal from average brain activity for a long time.
This is infinitely more simple than actual "mind-reading" and "mind-writing" which, as any neuroscientist will tell you, we don't have clue how to do.
And without invasive procedures.
What did they claim the chip was doing? It just looks like a monkey trained to play basic video games for food.
That chip could be the sticker of the backpack of a little Lego spaceman.
It ends up playing using only the neuralink when the joystick is disconnected.
I should have be more attentive (and up to date), that is impressive. I hope those allegations are false, no amount of progress can justify such lack of respect for the life of a primate.
Not even helping every human who lost the use of some or the whole of their body? Isn't being locked into your body for the rest of your life torture as well?
