Entrepreneur Bryan Johnson explains his decision to follow a plant-based diet in part due to the potential future dominance of AI, which he believes may one day be as powerful and dominant over humans as humans are over animals. Johnson consumes 130g of protein daily from plant-based sources, and his company Blueprint sells food regimens focusing on nutritious fruits, vegetables, and grains.

Johnson has extensive involvement in AI tech, with investments in companies like Extropic and the use of AI-based startup Ezra for full-body MRIs and CT scans. He also mentioned having a "Bryan AI" that has processed everything he's ever said in his pursuit of immortality. AI has the potential to revolutionize healthcare, but concerns remain about job losses and the spreading of misinformation through chatbots like ChatGPT.

With the possibility of AI taking over, Johnson's beliefs and investments reflect his awareness of the potential impacts of AI on society. Despite the growing influence of AI in various sectors, concerns persist about job displacement and the reliability of information provided by AI technologies.
