I am on X, however, and follow @XueJia24682 and see the advancements that, if the United States had developed them first, would be evidence that we're the greatest country on Earth. You know, stereotypical things like robots, food production, infrastructure, beautiful culture, etc.
Also, is communism in China getting it all done? I need more info.
I am going to have to post on the culture and government here to make this more well-rounded.
To me it seems like, with its greater workforce (being weaponized?), it is only a matter of time before China is seen as the world leader.
That is my very uneducated, underdeveloped, unresearched position.
