Optoelectronic intelligence

General intelligence involves the integration of many sources information into a coherent, adaptive model world. To design and construct hardware for general intelligence, we must consider principles both neuroscience very-large-scale integration. For large neural systems capable attributes photonics communication electronics computation are complementary interdependent. Using light enables high fan-out as well low-latency signaling across with no traffic-dependent bottlenecks. computation, inherent nonlinearities, speed, low power consumption Josephson circuits conducive to complex functions. Operation at 4 K use single-photon detectors silicon sources, two features that lead efficiency economical scalability. Here, I sketch concept optoelectronic hardware, beginning synaptic circuits, continuing through wafer-scale integration, extending interconnected fiber-optic tracts, potentially scale human brain beyond.
