As a shareholder I want a leader who knows how to let other people run the company also, so it doesn’t die with them. (Eventually we’re all headed there, right so…)

I feel like your argument is just "Jensen Huang was Nvidia, and without him the company is doomed", and that's a very strong claim that needs a lot more explanation, because it's certainly not an argument that any shareholder is interested in considering when the company continues to exist, its products remain important and in-demand, and there's a CEO vacancy to fill.

What skills, specifically? I can't imagine he's the only one who knows how to set up an incomprehensible corporate structure, nor do I think that's what people value about NVIDIA.
