Neuralink, started by Elon Musk, plans to implant its new brain chip, Blindsight, into a human in late 2025. This chip could help blind people see again. It’s a major move in neuroprosthetics.
What Blindsight Is
Blindsight is a brain-computer interface (BCI). It bypasses damaged optical pathways and stimulates the visual cortex directly. It doesn’t repair eyes. Instead, it uses technology to let the brain perceive vision without them.
Ultra-thin electrodes get implanted in the visual cortex. A small camera captures real-time images. An external unit processes these into neural signals. The signals go wirelessly to the implant.
The brain interprets them as visual information. At first, resolution will be low, but Neuralink aims for superhuman vision later, including wavelengths beyond normal human sight.
Getting to Human Tests
The FDA gave Neuralink a “breakthrough device” designation to speed up development, Initial trials will test safety and functionality. They’ll check if it can restore partial sight. Over time, Neuralink plans to improve resolution and capability.
What It Could Mean and What’s Hard
This could change life for blind people. But it’s not easy. Some say the plan’s too fast or tricky since brain signals are hard to read. Others worry about safety over time, ethics, and how it’ll affect society.
Elon Musk’s Take
Musk spoke in Wisconsin recently. He said,
“It will be low resolution at first, but over time, the impact will enable vision that is like superhuman.”
He sees it helping the blind see, the paralyzed move, and even boosting cognitive abilities.
Blindsight is a bold link between biology and technology. If it succeeds, it could improve millions of lives. With the first human implant nearing, everyone’s watching to see if this becomes reality.
