The document discusses two economic crashes - the bursting of the dot-com bubble in 2000 and the financial crisis of 2008. It notes that while confidence in the "New Economy" crashed after the dot-com bubble, the response was the rise of Web 2.0, which focused on social aspects rather than just products/things. It argues that while some were too exuberant about the potential of the dot-com era, the ideas underlying new technologies are still valid and promising.
