  • Moore's Law 2.0?

    In 1965, Dr. Gordon E. Moore wrote an article (PDF) based on a trend he noticed that the number of transistors in a dense integrated circuit (IC) doubles approximately every two years. Fueled by unrelenting demands from more complex software, faster games, and greater broadband video, this observation was later dubbed Moore’s Law and has held true for nearly 50 years. It became the de facto roadmap against which the semiconductor industry drives its research and development. But that roadmap may be faltering now due to fundamental physics limitations incurred at the incredibly small scales at which we fabricate chips. Can we find novel ways to circumvent these limits and thereby achieve Moore’s Law 2.0? If we are successful, what implications might such computational capacity have for society?

  • Beyond 3D Printing: Programming the Material World

    New technologies are converging in a cresting tsunami. Robotics, autonomous vehicles, big data, the “internet of everything,” nanotechnology and other technology sectors are being mashed up in ways incredible to those who studied engineering even as recently as the 1990s.

    In particular, 3D printing (additive manufacturing)1 revolutionizes the future with its potential to make almost any object, as well as to create complex objects impossible to fabricate via traditional manufacturing approaches. A wonderful aspect of 3D printing is its breadth of applications. From aerospace components to food, human organs, clothing, buildings – potentially world-changing 3D printing applications emerge seemingly every day.

  • The Next Wave: 4D Printing

    Programming the Material World


    3D printing (additive manufacturing) has been around for nearly three decades, but only in the last few years has it captured the imagination of millions of people with its potential to manufacture almost any object, as well as to create complex objects impossible to make via traditional manufacturing approaches. Three years ago, the Atlantic Council explored the implications of 3D printing in a groundbreaking report, Could 3D Printing Change the World?

    A new report by Thomas A. Campbell, Skylar Tibbits, and Banning Garrett, The Next Wave: 4D Printing - Programming the Material World, examines 4D printing, a new disruptive technology on the horizon that may take 3D printing to an entirely new level of capability with profound implications for society, the economy, and the global operating environment of governments and businesses alike. Programmable Matter (PM), here described as 4D Printing (4DP), has the economic, environmental, geopolitical, and strategic implications of 3D printing, while providing new and unprecedented capabilities in transforming digital information of the virtual world into physical objects of the material world.

  • Beyond Today's Internet

    When the precursor to today’s Internet, the ARPANET, had its first nodes connected in 1969, only a handful of computer scientists knew about it. Now most of the world is dependent on the Internet’s vast web of links, tweets, posts, and likes for commerce, communication, and socialization.

    But could the Internet of future generations be even more revolutionary? Keeping in mind that the Internet evolved largely without any central guidance – recently, the US government announcedit will “transition out of managing domain names and addresses for the Internet Corporation for Assigned Names and Numbers (ICANN)” – what new forms or functions will this global system take as technologies such as robotics, autonomous vehicles, ubiquitous sensors, and others move toward an online presence? To understand these changes, we trace the Internet through four major stages of Web 1.0 to 4.0.
