I'm not saying Huang is skill-less, and by making that claim in your comment, you are moving the goalposts. I am saying it is not obvious that he would have done genius-level better than a different CEO.

Your best claim is that Nvidia is the biggest company in the world; therefore Huang is a genius. Maybe; some days Apple is also in the running for biggest company in the world. By your metric Tim Cook is therefore a genius. This makes me seriously doubt your metric.

Tim Cook did not build Apple from the ground up. Steve Jobs did, and if he were still in charge he would still unquestionably be a genius.

You can doubt my metric, but it is quite difficult to grow a company to a trillion dollars while staying in charge the whole time.
