Elon Musk's Neuralink, a neurotech startup, has killed approximately 1,500 animals in the process of developing an implantable vision chip to cure blindness. Monkeys implanted with Neuralink brain chips suffered post-surgery, with one monkey scratching at the site until it bled and pulling out part of the device, while another experienced severe brain bleeding. Physicians Committee for Responsible Medicine urges Neuralink to halt animal and human experiments and focus on non-invasive brain-computer interfaces, but the company is still recruiting for human trials.Elon Musk's Neuralink, a neurotech startup, has killed approximately 1,500 animals in the process of developing an implantable vision chip to cure blindness.
