Which physical properties of 2D and layered materials can we exploit for powering the next generation of devices that power all of classical information systems?  And which 2D materials are showing promise to enable the future quantum information systems, and why? I will discuss the two questions above. The first question will lead us to the quantum mechanical roots of why current state of the art transistors are slipping away ~1000x more energy than what is needed for logic operations.  And more so than logic, the bottleneck of memory devices threatens to significantly throttle increased performance that smaller, faster and better transistors have to offer.  I will discuss why there is significant excitement in 2D materials - for improving the performance of 'classical' logic and memory devices such as the transistor and RAMs.  At least some aspects of future information systems will be performed non-classically.  I will discuss which families of 2D materials are making a case for such applications, and why.
