Odysseys in Technology: The Glacial Rate of Breakneck Change, lecture by Greg Papadopoulos
From abstract: "It's really easy to equate the breathtaking exponential growth in computing technologies with an underlying innovation in computing architecture. Nothing could be further from the truth. In this unabashedly personal perspective of our living computer history, Greg Papadopoulos distills what has -- and hasn't -- been happening in the design of computers over the past few decades, and uses that to make some predictions as to what the next few will bring. He discusses that, when you boil it all down, there are perhaps only four or five basic ideas in computing; everything else we experience are (just) constant factors."
