Yes, 100% agree.

The question is if China will do what all prime players do, which is become an empire that enriches itself at the expense of ther rest of the world.

Not being a massive a dick is a good strategy when you're #2. There are so many companies that do "the right thing" because it gives them a competitive advantage compared to their #1 competitor who is doing the "wrong thing" because they have the dominance to do so, but the instant #2 becomes #1, they adopt #1 strategies.

Perfect example is when X-Box tried to digitize games and limit physical media. Playstation countered with a brutal add on the one-step method to transfer your game to a friend (step 1: give them the game). Now that X-Box has fucked it's market position, it is Playstation that is pushing to end physical media.

The perfect world is one in which you don't have to trust anyone, where there is always a healthy ecosystem that gives you options and prevents any one controlling everything to their benefit.

But right now, the world's biggest problem is not China or Russia: it's the US.
