As from 2016, Elon Musk started a new company called “Neuralink”, having the threat of AI taking over the world he created the mission of merging it all. Artificial Intelligence and humans brain. What makes it possible is an almost non-invasive surgical operation, by a calibrated robot which implants threads as tiny as 4 μm to 6 μm in width between blood vessels in our brain. For comparison, human hair has 75 μm.
How does it work? In shortcut, these threads would be used as electrodes which fire electric signal to impact surrounding neurons in such a way to improve brain capabilities such as better memory, better mathematical reasoning, coordination or to help with things like depression and Alzheimer. Experiments on people are anticipated to begin in 2020. Is it the next step to a dystopian future or a beginning of a big advancement in technological progress for mankind?
