From the Paleolithic to the Neolithic era, the economy doubled in size every 250,000 years. From then until the Industrial Revolution, the economy doubled in size every 900 years. And form then until now, the economy began to double in size every 15 years.

If the singularity brings about another such change in the rate of economic doubling, it is possible that the economy would double in size every week as a result of the singularity. This makes sense, because machines would be performing the jobs that humans perform but, as is so characteristic of machines, they would be performing them more quickly and efficiently than human beings.

Wealth will probably have trouble diffusing among the human population after the singularity, since most humans will not be able to contribute anything to the economy that machines cannot do better. Wealth will then concentrate in the hands of those who own the machines.
