I have been hearing this talk since 2000. U.S. is still the super power of the world. U.S. companies are still the dominant global companies that power the world. Especially as European growth has stagnated. As Chinese growth has slowed.
US companies are spending 400B+ dollars on the AI Superintelligence trade this year alone. That is the next technological revolution and the only two competing is US vs China. While China has the advantage of ample power generation, US has the chip advantage.
I am not sure how you think the U.S. will fade into England like status when Microsoft, SpaceX, Nvidia, Apple, AMD, Meta, Google, Amazon, and hundreds of other U.S. companies control such a strong part of the global economy and technological IP. The world is heavily integrated into Western technological ecosystem. Even Iran that calls America the Great Devil is powered by Microsoft OS (including its military btw) and its domestic population is obsessed with Apple products.
The U.S. empire may be decaying (as is natural) but it controls most of the world’s most lucrative companies. Its downfall could take centuries, a timeline that far exceeds our lives.
