Radio-frequency chips — the parts in every phone, car radar, and satellite link that send and receive signals — have stayed a hand-crafted "dark art," mastered over years, even as CPUs and GPUs got designed by algorithm. Writing in IEEE Spectrum, Princeton's Kaushik Sengupta describes teaching AI to design these RFICs from scratch, with no human templates — and the results look nothing like human work. — Read the rest
