I'd reference the Nikkei 225 circa 1990 [1]. That graph is not inflation adjusted. Up to 1990 everybody thought Japan was well on its way to becoming the world's largest economy on an exponential and unstoppable economic acceleration. And it was unstoppable. Then it stopped.

I am not saying this will be the case, but rather that we're at what is likely the largest inflection point in modern history, and trying to predict where the world will be at in 10 years has become effectively impossible.
