Neuralink and beyond - How many people have had computer processor implants or other devices installed for better brain function or for acuity?

 As of July 2, 2024 

As of now, around 35 people have received long-term brain implants designed to interface with computers. Most of these individuals have implants from Blackrock Neurotech, known as the Utah array, which is widely used in academic research and clinical studies​ (MIT Technology Review)​​ (MIT Technology Review)​. These implants are primarily intended to restore lost functions in people with severe physical impairments, such as paralysis, by allowing them to control devices directly with their thoughts​ (Wu Tsai Neurosciences Institute)​.

Neuralink, a company founded by Elon Musk, has also begun human trials with its brain-computer interface (BCI), aiming to enhance communication and control devices through thought alone. While the technology is promising, it is still in the experimental stage and primarily targets therapeutic applications rather than enhancing cognitive functions for healthy individuals​ (Pew Research Center)​​ (Pew Research Center)​.

Despite the potential benefits, public opinion remains cautious, with many people concerned about the ethical implications and possible risks associated with brain chip implants. A 2021 Pew Research Center survey found that a majority of Americans are wary of the widespread use of brain chips for cognitive enhancement, viewing it as meddling with nature​ (Pew Research Center)​.

Overall, while the technology for brain-computer interfaces is advancing, its primary focus remains on medical and therapeutic applications, with consumer uses still being a future prospect.
