Tech billionaire Elon Musk has announced that his company, Neuralink, has successfully implanted a wireless brain chip in a human. Musk stated that “promising” brain activity was detected after the procedure and that the patient is recovering well. Neuralink’s goal is to connect human brains to computers to address complex neurological conditions. While several rival companies have also implanted similar devices, this milestone marks an important step for Neuralink. However, experts caution that true success can only be evaluated in the long-term. Musk’s claims have not been independently verified, and Neuralink has not provided any additional information about the procedure. Neuralink has faced criticism in the past for animal testing, and an ongoing investigation by the US Department of Agriculture is underway. The FDA granted Neuralink permission to test the chip on humans in May 2023, allowing for a six-year study. Neuralink’s first product, called Telepathy, aims to enable control of devices through thought and could benefit individuals who have lost the use of their limbs. While Musk’s involvement raises Neuralink’s profile, other companies in the field have a longer history and have achieved significant results.
