"combines previously incompatible: (1) lithium tantalate guiding light more efficiently than silicon, (2) copper instead of gold... semiconductor manufacturing process resulting in mirror-smooth surfaces allowing seamless optical/ electronic interface... runs stably without needing constant manual/ automated corrections... >400 Gbps data rate (80K HD video streams at once)... significantly less: energy consumption/ large-scale artificial intelligence model training costs... AI clusters, data centers"
