Chinese researchers build a light powered AI chip that diagnoses disease like a radiologist

This is the kind of hardware story that rarely gets attention next to model launches, but it points at a real bottleneck, the energy cost of running inference at scale. Trading electrons for photons is not a new idea in physics, but pairing it with a material like black phosphorus to hit both speed and accuracy on real diagnostic images is a genuine systems achievement, not just a lab curiosity. If this scales past a prototype, the pitch about bringing expert level diagnosis to places without reliable power or GPU access is the part worth watching, since that is a much harder problem than beating a benchmark.
