This was an interesting video. I was only able to watch half of it bc I found the guy to be extremely full of himself.
I do not personally have experience with export control investigations, but I do know people that do. The scenario he describes is very likely and what would be done to evade export controls. But he is still doing quite a bit of speculating.
What doesn't make sense to me is why Nvidia would risk this, it's not like there isn't a market for these chips that is willing to pay their asking price. A DOJ investigation/litigation/fines and the ensuing monitorship would easily cost over $500 million and could push $750 million.
Are export controlled chips finding their way into Chinese hands? Absolutely. At the scale he is alleging? I would like to see some actually proof.
