But given the rate at which technology is increasing, I quite easily see A.I.'s gaining in mental faculties and quickly overtaking dragons and I.E.'s in terms of thought processes and knowledge base. There is a virtual (no pun intended) guarantee that baring a complete halt of technological development that an A.I.s will become the dominant sentience in a reasonably short window, of say less then 100 years.
Rough estipate of the number of calculations per second in the human brain: ~10
14. [1]
Maximum human sensory bandwidth is ~10
8 bits per second.
While it is not possible to get a very exact estimate of the cost of a realistic simulation of human history, we can use ~10
33 - 10
36 operations as a rough estimate (

Eric Drexler has outlined a design for a system the size of a sugar cube (excluding cooling and power supply) that would perform 10
21 instructions per second. [2]
Another author gives a rough estimate of 10
42 operations per second for a computer with a mass on order of a large planet. [3]
A single such a computer could simulate the entire mental history of humankind by using less than one millionth of its processing power for one second.
