Instead, I saw a massive golden chandelier suspended in what looked like a giant refrigerator, surrounded by tubes and wires that belonged more in a science fiction movie than in a data center. "This," he said, "can theoretically solve in minutes what would take all the world's supercomputers combined thousands of years." I was skeptical.
