This 3D-printed #ai construct analyzes by bending light

Machine learning is everywhere these days, but it’s usually more or less invisible: it sits in the background, optimizing audio or picking out faces in images. But this new system is not only visible, but physical: it performs AI-type analysis not by crunching numbers, but by bending light. It’s weird and unique, but counterintuitively, it’s an excellent demonstration of how deceptively simple these “artificial intelligence” systems are.
