Elon Musk's Neuralink is set to implant its brain-computer device into a second human patient in a week or so. During a video update Wednesday, Musk hopes to have devices in patients numbering “in the high single digits” by the end of the year.

The first patient, Noland Arbaugh, faced device malfunctions post-surgery. In upcoming surgeries, Neuralink will make some changes to try to mitigate the issue of its electrode threads retracting from brain tissue, Musk said. Musk envisions this technology as a potential treatment for obesity, autism, depression, and schizophrenia.

The billionaire and several key Neuralink staffers also discussed future generations of the device. Musk said it should be possible for patients with older models to upgrade to newer ones. “You want the iPhone 15,” he said. “Not the iPhone 1.”

According to a report in 2023, thousands of people were in line, hoping to have the brain implant from Elon Musk's brain-computer interface company, Neuralink. It is reported that Neuralink is expected to achieve an annual revenue of up to 100 million US dollars within five years.
