From Restoring Sight to Reimagining the Brain, with Max Hodak

The brain functions as a computer, making it a primary target for medical engineering to restore lost sensory and motor capabilities. Max Hodak, founder and CEO of Science, details the development of the PRIMA retinal prosthesis, which recently received European regulatory approval to restore form vision in blind patients by bypassing damaged rods and cones. Beyond immediate medical applications, the discussion explores the "platonic representation hypothesis," which suggests that AI models and biological brains utilize similar geometric structures to represent concepts. This alignment validates the potential for high-bandwidth neural interfaces. Looking forward, the mission centers on achieving substrate independence and reducing human fragility, ultimately enabling humans to adapt to environments beyond Earth. By treating the brain as the central object of the human experience, these technologies aim to provide swappable, upgradeable parts that transcend traditional biological limitations.
