This is a nice way to put it.
Anticipate a world within your life time where China is the dominant economic, technological, military and cultural super power.
Anticipate jealousy, anticipate fear, but know that as Americans who have been top dog for decades there is nothing wrong with not being the best.
Additionally anticipate a changing world view less focused on the view that freedom and democracy as the only possible way to lead and anticipate that despite the fact that China is a communist country and centrally controlled they don't want conflict and they don't want total war.
China and the US are not perfect. The US needs to accept this fact and it needs to accept that another is about to take it's place as the top dog.
