This is my dumping ground for quotes and other stuff relating to the wonderful world of digital & communications.
The electrical efficiency of computing (the number of computations that can be completed per kilowatt-hour of electricity used) has … doubled every year and a half since the dawn of the computer age. Laptops and mobile phones owe their existence to this trend, which has led to rapid reductions in the power consumed by battery-powered computing devices. The most important future effect is that the power needed to perform a task requiring a fixed number of computations will continue to fall by half every 1.5 years (or a factor of 100 every decade). As a result, even smaller and less power-intensive computing devices will proliferate, paving the way for new mobile computing and communications applications that vastly increase our ability to collect and use data in real time.
