Musk technomancy
Neuralink is a brain implant with 1,024 5-micron-wide (very, very thin!) electrodes and includes sensors for motion, temperature and pressure. Ultimately, according to Elon Musk, the medical goal is for such implants to be able to control prosthetic limbs, alleviate memory loss, help with addiction and fix mental illnesses and vision and hearing impairments.
Musk has described it as “a Fitbit in your skull” and some of his more enthusiastic claims are that this technology could one-day record and replay memories and (due to the device’s wireless capabilities) enable telepathy – sending and receiving words, concepts and images.
All this sounds incredible and Neuralink is certainly a step up from what has currently been available to neuroscientists – the current Utah Array has 64 electrodes and installation can cause significant tissue damage on installation and removal.
Whilst Neuralink represents a huge step forward for neuroscientists, however, there are still plenty of unknowns to do with how neurons function and how this type of technology can remain in the brain for long periods of time without causing tissue damage or being damaged by the environment within the cranium and the human immune response. For all of Musk’s technomancy hype, Neuralink currently asks more questions than it provides answers to and there are still plenty of difficult barriers to overcome before any of the promised advantages are possible.
