Agreed, the focus on Jensen Huang's affairs, even with this Chinese "spy" are just a side show.
The more serious side of this is that NVidia, and specifically (but hardly only) Jensen have been knowingly supplying Megaspeed (and probably many more) Chinese proxy companies with GPUs, presumably well aware that the final customer was China in one form or another, which would be a felony if proved.
The US Commerce dept, and FBI, had been investigating Megaspeed until for unknown reasons (follow the money!) the Justice dept. told the Commerce dept. to stop the investigation. Trump appears friendly with Jensen, and effectively (but not legally) commands the DOJ, so it would not be surprising to find that he is the one who stopped this investigation. Trump had previously arranged for NVidia trade with China as long as the US government got a 15-25% cut, so to him this is all about money not AI or national security strategy.
The timing of this now coming out may be related to the midterms and change in balance of power, and an interesting question is who behind pushing this into the news? One possibility would seem to be the FBI, upset that this investigation had been shut down, realizing that that with the dems controlling the house and senate that Trump would have less ability to control it. The whole "having affair with Chinese spy" angle seems well designed to get media coverage. It's interesting who is behind resurfacing Jensen's multiple affairs with Nvidia staff - did the same party that pushed the Spy/Megaspeed story to this, or is this from people inside NVidia perhaps happy to pile on? Jensen does seem to have run Nvidia as his oen personal fiefdom, installing three family members there in high paid jobs, as well as his employee affairs, and presumably had his enemies there as a result. Jensen's rapid resignation perhaps reflects him realizing that his protection is gone and this is not just a media story that may blow over.
It seems that it's not only Jensen Huang that needs to be (and will be) investigated here, but also NVidia, and the Commerce department, and whoever ordered the investigation shut down.
One interesting practical aspect to this is does NVidia keep supplying GPUs to these Chinese proxy companies in Singapore and elsewhere, or does this now actually get shut down? It's crazy that there are US companies starving for NVidia GPUs while NVidia was preferentially selling them to companies like Megaspeed instead. If this changed, would it end the US GPU shortage?
