In 2016, when Jensen Huang launched the first DGX-1, almost no one paid attention at the event. Jensen Huang said to Elon Musk: At that time, it was dead silent, and only one person showed interest—that person was you. Nine years later, the DGX Spark he introduced is only the size of a desktop computer, yet its computing power is five times that of the first-generation DGX-1. At SpaceX's rocket factory, Jensen Huang deliberately made Musk admit: What I build is bigger than yours. Musk replied with a laugh: True, your data center scale is indeed massive.
