# How To Build The Future: Max Hodak Source: https://www.youtube.com/watch?v=5gspRJVp9dI Recap page: https://rapidrecap.app/video/5gspRJVp9dI Generated: 2026-03-09T14:33:19.657+00:00 --- ## Quick Overview Max Hodak, co-founder of Neuralink and founder/CEO of Science, predicts that within 10 to 20 years, brain-computer interfaces (BCIs) will be able to restore significant functionality to people with severe disabilities, such as those with blindness or paralysis, by bypassing damaged neural pathways and directly stimulating the remaining neurons or sensory organs. **Key Points:** - Hodak believes it is very possible that the first people to live to 1000 years old are alive right now, suggesting radical life extension is nearing. - Science recently announced that over 40 people have received their first BCI treatments, which are small 2mm x 2mm silicon chips implanted under the retina. - The BCI device works by projecting an image onto the retina via a laser projector, which then excites the photoreceptor cells (rods and cones) that are still alive. - The technology allows for restoration of vision by bypassing dead rods and cones, and Hodak is also excited about the potential for motor control restoration for paralyzed individuals. - Hodak contrasts the drug discovery approach with the neuroengineering approach, noting that the latter can be much more powerful for treating conditions like macular degeneration and paralysis. - The major challenge for BCI development is creating a system that can process the vast amount of information flowing from the brain (estimated at 40 bits per second) in a way that is intuitive and doesn't overwhelm the patient. - Hodak notes that the ethical implications of highly advanced, conscious AI systems are something that must be considered, but he believes the immediate focus should be on treating the most disabled populations. ![Screenshot at 00:04: Max Hodak discusses the PRIMA vision restoration technology, detailing the small 2mm x 2mm silicon chip implanted under the retina that uses light flashes to stimulate surviving photoreceptor cells.](https://ss.rapidrecap.app/screens/5gspRJVp9dI/00-00-04.jpg) **Context:** This interview features Max Hodak, co-founder of Neuralink and the Founder & CEO of Science, speaking with Garry Tan, President & CEO of Y Combinator, on the 'How To Build The Future' podcast. The discussion centers on the advancements and ethical considerations surrounding brain-computer interfaces (BCIs), specifically referencing Science's work with their PRIMA vision restoration technology, which involves implanting micro-electrode arrays to stimulate the retina. ## Detailed Analysis Max Hodak, co-founder of Neuralink and founder/CEO of Science, discusses the potential of brain-computer interfaces (BCIs) and their company's progress. Hodak states his belief that the first people who will live to 1000 years old are likely alive today. He highlights Science's recent announcement that over 40 people have received their PRIMA vision restoration implants, which are tiny silicon chips placed under the retina. These chips function by receiving light projected from glasses and exciting the remaining healthy rods and cones, effectively bypassing the dead ones. Hodak emphasizes that this neuro-engineering approach is far more powerful for treating conditions like macular degeneration and paralysis compared to traditional drug discovery methods, though it requires sophisticated engineering to manage the high bandwidth of neural information. He notes that while the brain is highly plastic, translating raw electrical signals into coherent perception (like reading letters) requires careful training, but the potential for restoring function, like motor control for the paralyzed, is immense. Hodak also touches upon the ethical concerns surrounding artificial intelligence, contrasting the current state of AI (which he compares to a simple input/output system) with the goal of creating conscious, highly intelligent machines that might eventually surpass human capability. He concludes by noting that Science is focused on near-term, tangible benefits like vision restoration for the most disabled patients, rather than purely speculative AI development. ### BCI Progress and PRIMA - Hodak reports over 40 patients have received Science's PRIMA implant, a 2mm x 2mm silicon chip that restores vision by stimulating surviving photoreceptors via a laser projector in glasses - The device bypasses dead rods and cones, allowing patients to perceive flashes of light which the brain learns to interpret. ### Motor Control and Plasticity - The technology also holds promise for restoring motor control in paralyzed individuals, leveraging the brain's inherent plasticity to learn new representations (like motor commands) from the electrical signals. ### Ethical Considerations & AI - Hodak distinguishes between current AI (which he sees as simple input/output processing) and future superintelligent AI, stressing that the ethical questions surrounding highly advanced AI are important but secondary to immediate medical applications like vision restoration. ### Company Focus & History - Science's initial focus was on the retina, but they expanded to other areas like motor control. The company was founded in 2016, inspired by early BCI research from the 1990s, and aims to solve fundamental problems in healthcare rather than just creating a 'product'. ### Future Outlook - Hodak believes that in 10-20 years, such technologies will be common enough that people will be able to 'boot up' functionality, such as restoring vision or motor control, to people with severe disabilities. ![Screenshot at 00:01: Max Hodak is introduced as the Founder & CEO of Science, joining Garry Tan for the interview.](https://ss.rapidrecap.app/screens/5gspRJVp9dI/00-00-01.jpg) ![Screenshot at 01:11: Max Hodak uses hand gestures to describe the small size of the retinal implant, comparing it to a tiny silicon chip that acts like a solar panel for the eye.](https://ss.rapidrecap.app/screens/5gspRJVp9dI/00-01-11.jpg) ![Screenshot at 02:22: Max Hodak explains that current BCI technology is more about 'restoration' than creating an artificial reality like 'The Matrix', focusing on bypassing damaged neural pathways.](https://ss.rapidrecap.app/screens/5gspRJVp9dI/00-02-22.jpg) ![Screenshot at 08:07: Max Hodak illustrates the difference between the optic nerve's limited signal capacity and the high bandwidth required for complex perception, which BCI aims to address.](https://ss.rapidrecap.app/screens/5gspRJVp9dI/00-08-07.jpg)
