    Scientists have cited technical challenges for Neuralink. In 2017, a journalist at the IEEE Spectrum Magazine had asked for comments from five researchers that had been working on BCI implants, including Thomas Oxley that invented the Stentrode.[45] At a live demonstration in August 2020, Musk described their device as "a Fitbit in your skull". Several neuroscientists and publications criticized these claims.[11][12][46] MIT Technology Review accused the demonstration of having the main objective to "stir excitement", adding that "Neuralink has provided no evidence that it can (or has even tried to) treat depression, insomnia, or a dozen other diseases that Musk mentioned in a slide".[11] Andrew Jackson, professor of neural interfaces at Newcastle University, also commented on the presentation to the BBC. To Musk's statement that he found Neuralink's advancements to be "profound", Jackson responded, "I don't think there was anything revolutionary in the presentation."[47]

    Thiago Arzua of the Medical College of Wisconsin argued that what Neuralink does is not novel and that ideas for a brain–machine interface (BMI) is at least 50 years old.[48] He cited successful control of a robotic prosthetic arm by a man that gave him haptic feedback, which he used in 2016 to give President Obama a fist bump.[49] Arzua said that the 2020 Neuralink presentation "showed little more than a flashy new design for a BMI with more electrodes".[48]
