Von Neumann architecture vs Harvard architecture, futuristic computer room, dim blue lighting, rows of sleek servers, wires and cables neatly organized, a large transparent glass wall separating the room from the main laboratory, a whiteboard filled with complex diagrams and equations in the background, a young programmer, male, 25yo, messy brown hair, black-rimmed glasses, casual wear, standing, leaning against a desk, intensely staring at a computer screen, fingers rapidly typing on the keyboard, a Harvard architecture diagram displayed on the screen, a Von Neumann architecture blueprint spread out on the desk, pencils and markers scattered around, a small robot vacuum cleaner quietly moving in the corner of the room.
