He does not seem vital to the company at all
I suggest reading Tae Kim’s book on the company. Unless Mr. Kim is lying - and he has no incentive to - NVIDIA is very much an extension of Jensen. His management shaped it to the core. It would survive his ousting, but not unscathed. Comparisons to Jobs & Apple are not unwarranted.
I guess we'll find out
it may turn out that his absense might be vital to the companies future.
He's been behaving like a sugar hyped child over the last 15-20 years imho.
Can you please elaborate on why? He seemed like a luminary from what little knowledge I have. (Very well spoken, wide domain knowledge, obviously made the right bets, etc.)
