Elon Musk is turning millions of Tesla cars equipped with AI4 chips into personal AI agents. These vehicles will run Tesla/xAI's Digital Optimus while parked, acting as smart assistants for their owners and potentially generating extra income through the sharing economy. Currently, Tesla has around 3 million vehicles globally, meaning each car can utilize its AI capabilities when idle. According to Tesla's plan, owners can choose to authorize their vehicles to serve the public AI network during downtime, earning revenue in return. This mechanism not only enhances resource utilization but also provides owners with a brand-new income stream. However, most people haven't realized that this approach could disrupt the traditional car rental market. Unlike the usual concept of car-sharing, the dynamic involvement of AI agents offers owners a more flexible revenue model than traditional rentals. This strategy isn't limited to transportation but extends into new areas of life services, challenging existing economic models. Investors should keep an eye on AI chips and autonomous driving-related sectors, as well as the potential emergence of a secondary economic market. This trend could accelerate the commercial application of AI in the Internet of Vehicles, transforming the profitability models of the transportation services and automotive manufacturing industries. Tesla owners may unknowingly be becoming pioneers of the AI economy, and those unseen disruptive changes might just be the true wealth hubs of the future.
