Nvidia CEO Jensen Huang addressed a question about employees in "semi-retirement" mode at an internal all-hands meeting. The question highlighted tension among employees about some taking it easy due to significant wealth from Nvidia stock gains. Insiders said Nvidia's employee-focused culture and hands-off management style, coupled with the company's dominance in chips, maybe allowing some staffers to coast through work while still being richly compensated. Nvidia's explosive revenue growth means prospects have it easy with few customer complaints. But Huang warns employees not to rest on their advantages as competition grows.
