Tesla’s Optimus humanoid robot is promoted as a future mass-market product. Elon Musk claims it could automate most human labor for $20,000 each. He predicts public sales by end of 2027. Other leaders like Marc Andreessen and Jensen Huang also forecast rapid humanoid robot advances. Morgan Stanley projects 1 billion humanoid robots by 2050, creating a $5 trillion market. Researchers argue current AI may not suffice for real-world robotics. Yann LeCun states no company knows how to make humanoid robots smart enough yet. Jonathan Hurst notes making robots move like humans is far harder than making them look human. Google DeepMind’s ALOHA 2 robot uses AI to perform tasks like packing a lunchbox. Its Gemini Robotics model is a vision-language-action system trained on human demonstrations. Such models still fail on tasks outside their training data. Some propose world models as a better path to general robotics. World Labs raised $1 billion and was acquired by AMD for $8.2 billion.
