Woofun AI notes that Serenity identifies a 'new Cold War' emerging in the US-China AI competition, characterized by diminishing restraint from mutual supply chain dependence. The analysis highlights that despite claims by Chinese firms like 360 regarding offensive cyber capabilities, US AI giants such as Google and Meta are unlikely to reduce capital expenditures. This geopolitical tension centers on superintelligence, involving complex export controls among mega-corporations in the US, China, and Japan. A critical paradox persists: the US depends on China for rare earth materials, while China relies on EUV lithography and EDA tools from Europe and the US. Consequently, chip exports from NVIDIA and AMD to China remain linked to rare earth supplies. Serenity emphasizes the urgency for the US to build an independent rare earth supply chain and avoid tariff conflicts with key allies like ASML and Ulvac to preserve negotiation leverage, warning that strengthening Chinese autonomy is making this deterrent interdependence increasingly fragile.
