Go Big!
April 2018

I was fortunate to enter computing in the era of site funding by the Defense Advanced Research Projects Administration, whose sustained investment of $10M/year (inflation adjusted) enabled the undertaking of bold transformative ideas. Large-scale funding enables examination of larger questions that cross problem spaces, systems, abstractions, even fields. I believe the need for large investments has never been greater.  View full article
