China's humanoids were everywhere at America's top tech show An attendee shakes hands with a PaXini humanoid robot during the annual CES technology show in Las Vegas, Nevada, on Wednesday. One of Tesla CEO Elon Musk's worries was on full display at technology show CES in Las Vegas this week. Chinese-made human-like robots were everywhere across the exhibition floor, playing table tennis, sweeping floors and practicing kung fu. China's latest robotics innovations were delivered to the heart of America's technology showcase, serving a constant reminder of the technological race between the world's two biggest economies. While Santa Clara, California-based Nvidia and Advanced Micro Devices hosted keynotes touting ever faster artificial intelligence chips, a legion of budding Chinese robot creators occupied much humbler booths with machines giving life to the notion of physical AI.
