Reflections on science, technology, and computing — leavened by personal experience


An economic and cultural chasm, a digital divide, separates the digitally connected from those who lack the ways or the means to join the digital community. In a knowledge economy, the separated are cut off from a plethora of services, educational materials, and business prospects.

Broadband networks, wired and wireless, are the oxygen that lets the world of devices and services breathe. However, the air remains perilously thin. For many, digital inclusion remains a dream, rather than a reality.

Use of the word “computer” conjures certain images and brings certain assumptions. One of them, so deeply ingrained that we rarely question it, is that computing is digital. It’s time to reconsider analog computing as an element of computer system design, particularly in a world of near threshold voltage designs, dark silicon, exascale computing and…

Our run of good luck is over. We need new, integrated design methodologies and rich collaborations that consider end-to-end design and capability. In many ways, this is a return to the past.

Today, I testified to the Subcommittee on Technology and Innovation of the U.S. House of Representatives Committee on Space, Science and Technology. The topic of the hearing was “The Next IT Revolution?: Cloud Computing Opportunities and Challenges.” This is an exciting time, when computing can be a great equalizer, providing access to the world’s knowledge…
