Timeline: The Advance of the Data Civilization

In 2009, English scientist Stephen Wolfram started a website–an “answer” engine–to redefine how information is gathered on its greatest-ever conduit. In this timeline, he catalogs “how our civilization has systematized knowledge, and gradually made it amenable to automation. This is about data and how it came to be the way it is in our world.”
