The Computable Knowledge Revolution is rather like what Richard Feynman said about quantum mechanics "If you think you understand quantum mechanics, you don't understand quantum mechanics." The term computable knowledge itself is associated with Stephen Wolfram.
It involves linking computation and knowledge. At the simplest level it means being able to ask Wolfram Alpha where the international space station is at the present time. The answers to questions are not simply provided by accessing a structured database but by computing the answer beginning from structured data. Wolfram is also automating algorithm discovery that no human would have discovered. Wolfram does so by "mining" the computational universe for algorithms that can be applied to a broad range of applications.
Wolfram also indicates they will be offering something beyond on-demand answers to queries moving to a sensing of what you should know about which implies a "personal assistant" capability that could be augmented over time. They are also moving the Wolfram language capablity closer to the end user via mobile and other vehicles.
Wolfram implies that he has found something far deeper and related to his work "A New Kind of Science" that implies an underlying order to the universe that is computable.
It has not been characterized as yet by Wolfram but broadly hinted at. If anyone else but Wolfram had suggested anything like what he is talking about it would be dismissed out of hand. Wolfram could be a potential source for the Singularity.
