NVIDIA Founder Jensen Huang's biographer Stephen Witt said the billionaire's "humble" image is an act he performs not for the observer but to "flatter himself". "Huang went to considerable lengths to cloak his arrogance...He tipped a waitress $1,000 (over ₹94,000)...Over time...I began to suspect this was an act," Witt said. He added that Huang was "abusive" and intolerant towards disagreement.
