We have been used to high claims from Elon Musk, so high that seem impossible. Quite a bit of them, indeed, requires a reality check and need to be taken with much more than a grain of salt.
However, we have also seen that, may be with some downgrading and over a longe period of time, a number of his prediction turn out into reality. Hence, it is good to pay attention to his vision, since he is using that vision as a beacon for concrete implementation.
In this specific instance Elon is foreseeing (in the not distant future) the implant in the brain of a Neuralink chip, able to harvest electrical signals from over a thousands micro areas in the brain, and to use software to interpret those signals to control an external device, in this case a smartphone, with a precision and speed that may exceed the one we have using our thumb.
The tweet has been flanked by the release of the video I have included below. Please, watch it because it is amazing. You see a monkey that has been trained to use a joystick to control he cursor and then to play Pong. The training went both ways: the monkey learnt how to move the joystick to control the cursor and the software learnt what was going on in the monkey’s brain, in terms of electrical activity picked up by two implanted Neuralink chips wirelessly connected to a computer, thus associating specific electrical activity in the brain with the “intention” to move the cursor one way or the other.
Once the software has been trained the chips and the software could control the cursor directly from the brain (or mind?) and you see in the video how good the monkey has become in playing Pong just using his brain. It is most notable the accuracy and the speed of the interaction, something that indeed supports Elon claims that in the future we would be able to establish a radio link with our smartphone. The chip in our brain and the one in the smartphone will be able to communicate with one another creating a seamless interface. Notice that, in perspective, the chip from the smartphone can send signals to the chip implanted in our brain to improve the communication effectiveness. In the video you see that this backward loop with the monkey’s brain is achieved through a straw that delivers some “good” stuff to the monkey, motivating it to stick with the game. In our case one might think of signals to the implanted chip stimulating the release of endorphins …
Plenty of lights and dark, dark shadows ahead. Of course, saying that a technology will be available does not mean it will be used. Elon is careful to highlight the positive aspects, envisaging implants to help paralysed people, and we all see the benefit there. Yet, it is a Pandora vase: once opened it is difficult to predict the outcome.
What is this connectivity could provide a real augmentation, and advantage to a person? Will there be some that will ask for the implant to be augmented? Difficult to say that this will never happen! Are we going to have an augmentation divide as today we are facing a digital divide?
