Open weight models, for example, are forever. Proprietary models are intentionally building a moat to extract more value from people. I know which one I prefer.
A lot of China fearmongering (in general, not you in particular) is just xenophobia. You will see the argument that the US has to do imperialism because if it doesn't, then China will become dominant and do the exact same sins. It's also a bit of a self-report: we tend to assume other people will act like us if given the chance so any accusation is really a confession.
When it becomes dominant, China’s sins will probably be very different from the USA’s, but they are still going to be there.
Consider Xi Jinping Thought on Ecological Civilization doctrine [1]. At the UN Summit on Biodiversity in 2020 Xi Jinping said [2]. He is saying that the world cannot support the developing world living in a resource-intensive way that Western societies currently do and you need a more ecological way of living. So when China massively pushes solar and other renewables, it's just the natural extension of their political philosophy.
The US, on the other hand, is just 5 companies in a trench coat.
