1. Late one night, a delivery driver pulled up outside Valley Health Center. As he unloaded boxes, he swore he heard faint laughter coming from inside the building. Curious, he peered through the window and saw only empty rooms. Suddenly, an old nurse appeared in the hallway, smiling warmly. ‘Just our new AI doctor,’ she said. ‘He’s learning to laugh.’ The delivery driver left, shaking his head but laughing too—maybe it was just the stress of a long shift.
