I'm still reflecting on my last conversation with AI. A new brain interface technology has piqued my curiosity. This technology can restore sight to the blind and is actively preparing for human trials. Its working principle is as follows: a smartphone captures images through its camera and transmits these frames one by one to an AI chip implanted in the brain. The chip decodes the pixel information from the input images and stimulates the corresponding brain nerves, allowing the brain to perceive the image as if it were seen with the naked eye.
As long as AI processes a sufficient amount of information and achieves a high resolution, the images presented in the person's mind become incredibly real for the blind. Imagine that the image sent through the brain interface is an apple, but the AI chip interprets it as a pear; the blind person would be 100% certain that what they see is a pear, not an apple. This made me deeply contemplate: our world is also formed by our interpretations of the signals we perceive through our five senses. Is our brain essentially a chip that receives input signals and interprets them based on pre-stored information to create the images we see? So, have we already been living in a virtual world? Will brain interfaces and the metaverse take us into an even deeper virtual reality? What does the real world truly look like? Does it originally contain nothing?
