Max Hodak discusses Science’s retinal implant: a 2mm device that restores rudimentary black-and-white vision by bypassing damaged photoreceptors and leveraging neuroplasticity. While adult patients born blind face perceptual learning challenges—including distinguishing hallucinations from real input—over 40 trial participants have regained functional vision, with one reading a novel after years of blindness. The technology targets multiple causes of blindness and aims for near-native acuity, color, and field of view within 5–10 years. Science’s broader pipeline includes biohybrid neural interfaces using stem-cell-derived neurons and long-term perfusion systems reimagined from ECMO. Hodak traces his path from Transcriptic to Neuralink, emphasizing BCIs as civilization-scale tools—not incremental upgrades—and ties their acceleration to an inflection point around 2035. He expresses deep optimism: BCIs will reshape cognition, communication, and human potential in ways comparable to the early PC revolution, complementing rather than competing with AI.
