"If you remember nothing else about models, remember this: their weakness is they are built on a host of assumptions, and therefore are only as good as the assumptions on which they are built. Some assumptions are obviously unrealistic and couldn't possibly hold; some happen to be overtaken by events."

Undeniable. The following video provides some insight into where economics is headed over the next few decades:

While the level innovation that's being integrated into the discipline is certainly quite exciting, it is also quite worrisome as economic variables, like financial markets, are clearly non-stationary. For now, academic economics is shackled by baseless assumptions or irrelevant mathematical models.
