Some researchers are skeptical that a model trained on language alone, or even language and images, could ever achieve humanlike intelligence. “There’s too much that’s left implicit in language,” Ernest Davis, a computer scientist at NYU, told me. “There’s too much basic understanding of the world that is not specified.” The solution, he thinks, is having AI interact directly with the world via robotic bodies. But unless robotics makes some serious progress, that is unlikely to be possible anytime soon.
