In a small, sparsely furnished room, a young boy in a black T-shirt backs himself into a corner. He’s cautious. Cameras capture his movements, and microphones record every sound. But this doesn’t intimidate him; he doesn’t even seem aware that he’s being observed. His mom, sitting nearby, is not the object of his focus either. Brian (his name has been changed here to protect his privacy) is autistic, and he’s staring across the room at a two-wheeled, gray, humanoid robot with big, cartoonish eyes.
