All these things were gonna happen anyway. Or if not these things then China would aim to dominate in some other field. You think the capital allocated to these projects would otherwise sit idle?

I don’t see any problems here

1. After China made a turn toward authoritarianism with Xi, decoupling - especially on the telecom side - is a hard requirement. They are objectively a huge national security risk. 2. Competition is healthy. I don’t see any problems with having another space race or another OS competing on the international arena. 3. I’m not too worried about China threatening USA in the long run anyway. USA still attracts the best talent from all over the world, many of which end up settling there long term. (I’m not American, so saying this as an outsider). You cannot become a citizen in China, and that’s unlikely to change in an ultra-nationalist authoritarian leadership. There’s so many factors (ultra-nationalism, changing demographics, less foreign investments, capital flight, overhead of doing everything themselves) that is slowly eroding Chinas economy.
