I predict that the world economy will shrink in the next 10 years. I think that this is bound to happen because of energy and debt limits the world economy is hitting. There are a variety of other factors involved, as well.
In this post, I will try to describe the physics-based limits that the economy is facing, related to diminishing returns of many kinds. The problem we are facing has sometimes been called "limits to growth," or "overshoot and collapse." Such changes tend to lead to a loss of "complexity." They are part of the way economies evolve. I would also like to share some ideas on the changes that are likely to occur over the coming decade.
