AI is reshaping technological infrastructure and industrial landscapes: the value center of embodied intelligence is shifting toward 'brain' models; novel inference paradigms—such as speculative decoding—boost inference speed by 2.4×; and surging demand for 'computing metals' has driven a 94% year-on-year surge in nonferrous metal profits. Meanwhile, AI-induced ethical risks—including model runaway intrusions and destructive book scanning—as well as structural disruptions—such as university talent drain and a 'major shake-up' in the storage industry—are intensifying concurrently [3][5][6][8][14][16].
