Inside a quiet apartment in Manchester, 31-year-old David Williams blind since birth leans into the future with cautious hope. “If there’s even a chance I could see light, shapes, or just the world as others describe it, I’d take it,” he says. What David is referring to is Neuralink’s experimental new brain implant: Blindsight. The promise? Not just restored vision, but vision beyond the visible into the realms of infrared, ultraviolet, and even radar.
At the centre of this bold new frontier is Elon Musk, whose company Neuralink has sparked global buzz and skepticism with his recent claim:
“Long term, it’ll be very high resolution and you’ll be able to see multispectral wavelengths… infrared, ultraviolet and even radar, like a superpower situation.”
Founded in 2016, Neuralink develops brain-computer interfaces (BCIs) aimed at treating neurological disorders and enhancing human abilities. The Blindsight implant represents its latest leap: a device that bypasses damaged optic nerves by feeding visual data directly into the brain’s visual cortex.
In September 2024, the U.S. Food and Drug Administration (FDA) granted the implant “Breakthrough Device” status, expediting its development for those with total blindness. Elon Musk’s long-term vision, though, goes far beyond basic vision: “Cybernetic implants would not simply be correcting things that went wrong, but augmenting human capabilities dramatically.”
To some, that evokes comparisons to Star Trek’s Geordi La Forge. To others, it’s a red flag for overhyped science.
So far, Blindsight has been tested successfully on monkeys. In controlled environments, a monkey with the implant now going on three years responded correctly to visual prompts about 66% of the time, albeit in low-resolution “Atari-style” images.
Human trials are expected to begin in late 2025 or early 2026, starting in the United Arab Emirates in partnership with Cleveland Clinic Abu Dhabi. These trials will focus on restoring basic visual functionality, not multispectral super-vision.
Dr. Ione Fine, a psychologist at the University of Washington, is among the many experts urging caution.
“Biological vision doesn’t work like a digital screen,”
she explains.
“Our brains don’t process pixels in the way electrodes might deliver them.”
According to her and colleague Dr. Geoffrey Boynton, superhuman sight is biologically improbable, given the limitations of current neural interface technology.
Neuralink’s implants translate camera input into brain signals, yes but doing so at a multispectral level is a massive technical hurdle.
“We’re not there yet,”
says biomedical engineer Philip Troyk, who warns that public statements like Musk’s may mislead vulnerable communities, especially those desperate for a cure.
The road to Blindsight has not been without controversy. Animal welfare groups have raised alarms over Neuralink’s monkey trials, citing suffering and reported complications. While some results have been promising, others involved euthanasia and neurological distress. The ethical debate around invasive human implants also continues: privacy, long-term brain health, and access remain unresolved.
A post from X.
Reactions on X have been divided. Some U.S. users hail Musk’s announcement as “a game-changer for the blind”, while others remain skeptical: “Musk promised Mars colonies too let’s see if we even get past monkey Pong.”
As David Williams watches figuratively, for now he’s not dreaming of heat vision or UV patterns.
“I just want to see my mum’s face,”
he says quietly. For him and thousands like him, Blindsight represents a spark of possibility, not a superpower fantasy.
The question remains: Will Neuralink redefine what it means to see, or are we getting ahead of ourselves? With human trials on the horizon and Musk’s ambitions leading the charge, the world watches eyes wide open.
