Nvidia looks more like Apple than Cisco in 2000, because its demand is more durable and its lock-in stronger. Cisco had a few months of cancellable backlog and over-levered telco customers such as WorldCom and Global Crossing that went bankrupt, and its boxes commoditized. Hyperscalers now hold over $2.3T of cloud backlog stretching years, funded by very strong balance sheets. CUDA, accelerators, networking and systems integration create switching costs behind margins nearly twice Apple's. x.com x.comÂ
