Few would expect the future of artificial intelligence (AI) to depend on Eindhoven, a quiet Dutch town. Yet just beyond its borders sits the headquarters of ASML, the only company that makes the machines, known as lithography tools, needed to produce cutting-edge AI chips. ASML’s latest creation is a 150-tonne colossus, around the size of two shipping containers and priced at around $350m. It is also the most advanced machine for sale.
