A flat structure means nobody is a clear competitor with Huang for the top job. If Huang was able to get his way as was, adopting a more traditional structure would have just made somebody else a significantly more powerful #2. A lack of a clear successor might make the transfer of power rougher unfortunately.

Huang's net worth is over $200B, high enough to be in the world top-ten. He has been very well compensated by Nvidia. Either he decided he has enough money at some point or his current compensation numbers are just marketing. The real numbers were clearly much higher in the past, if not presently.

I suspect he's going quietly because the scandals haven't finished emerging yet[1]. At this point, it wouldn't surprise me if somebody has photos of secret Nvidia bunga bunga parties. I do find it interesting that Americans will tolerate lies, murder, and all sorts of other things from their highest elected officials but, if a CEO is revealed to be overly randy, he's got to go.
