Elon Musk and Max Hodak founded Neuralink along with several other people in 2016, and Musk has invested millions of dollars of his own money into the venture. Last year, Stat News reported that some former employees described a chaotic internal culture at Neuralink, saying that its scientists weren’t always given enough time to complete projects. Neuralink is focused on developing brain-machine interfaces. In March 2021, the company posted a video to YouTube that appeared to show a monkey with a Neuralink implant in its brain moving a cursor on a computer screen using only its mind. Some in the scientific and medical communities have criticized Neuralink and are skeptical of its scientific claims.
