The CEO spends half of his time directly talking to engineers because code is the "only source of truth."
When engineers say they lack GPUs, Musk asks twice but it’s not resolved, he directly calls the manager: "Double the cluster." The manager says to wait half a year, Musk responds: "I'll talk to Jensen Huang."
He is a hammer, personally smashing through all bottlenecks.
Harsh, but the reason top talent follows is because—here, only efficiency and results matter.
