Tesla's Optimus humanoid robot faces skepticism despite CEO's 2027 public sale prediction

Tesla's Optimus, an AI-powered humanoid robot, has been shown performing tasks like dancing, vacuuming, and handing out items, with CEO Elon Musk predicting it could be available to the public by the end of 2027 and potentially automate most human labor for as little as $20,000 each. While figures like Marc Andreessen and Jensen Huang predict massive growth, including a $5 trillion market by 2050 according to Morgan Stanley, AI expert Yann LeCun said that no company building humanoid robots currently knows how to make them smart enough to be useful, arguing that current AI struggles to master the infinite variability of the physical world.
