Artificial intelligence has ignited a massive global race for computing power, but the ultimate bottleneck to this technological revolution may not come from advanced silicon chips. Instead, it may come from a far more traditional commodity: copper. Every AI query routed through a neural network travels through a complex physical architecture packed with copper-intensive infrastructure. From high-voltage power cables and distribution transformers to liquid cooling systems, electrical substations, server racks, and long-distance transmission lines, copper is the indispensable element making artificial intelligence ...
