Tesla CEO Elon Musk has suggested that the rise of artificial intelligence and robotics could make traditional currency obsolete, while Bitcoin might endure as a measure of value. In a podcast with Nikhil Kamath, Musk envisioned a future where AI and robotics fulfill human needs, potentially eliminating the need for money as a labor allocation tool. He emphasized energy as a 'fundamental currency' and highlighted Bitcoin's proof-of-work mechanism, which ties digital value to real-world electricity and hardware costs.
