Big tech steps up push into physical AI

Big tech companies are moving faster into so-called physical AI that applies AI in the real world, including robots, cars and drones, as they seek to secure an early lead in a market seen as smaller than chatbots for now but with high potential. Nvidia, AWS, SoftBank, Anthropic and Xpeng are among those expanding initiatives. South Korean companies and institutions are also stepping up projects, funding and partnerships, even as concerns persist about data shortages and reliability.
