U.S. automakers' presence at the Consumer Electronics Show (CES) in Las Vegas has diminished, with autonomous vehicle technology companies and Chinese automakers filling the void, according to TechCrunch Mobility. The shift highlights the increasing importance of "physical AI," a term popularized by Nvidia CEO Jensen Huang, which refers to the application of artificial intelligence in the physical world.

Physical AI, also known as embodied AI, combines AI models with sensors, cameras, and motorized controls to enable devices like humanoid robots, drones, autonomous forklifts, and robotaxis to perceive and interact with their surroundings. This technology allows these devices to understand their environment and make decisions based on real-time data.

The Consumer Electronics Show featured a strong presence from companies specializing in autonomous vehicle technology, including Zoox, Tensor Auto, Tier IV, and Waymo. Waymo, notably, rebranded its Zeekr RT model. Chinese automakers such as Geely and GWM also showcased their latest advancements in the field, alongside software and automotive chip companies.

The rise of physical AI signifies a move beyond purely digital applications of artificial intelligence, with potential implications for various industries, including transportation, logistics, and manufacturing. The technology's ability to automate tasks and improve efficiency is driving its adoption across different sectors.
