Jon Summers on why we need to go into reverse to go forward

03 July 2020, 11:41

Jon Summers were featured in DCD Magazine Issue 36 – Are You Ready for Climate Change? in the section Future forecast.

We are now in the defining decade where the only way forward is to operate digital processing without losing information – so that the process can be reversed to recover its original state. At the center of thermodynamics and information theory is the idea of reversible computing, where the operations are adiabatic, and energy is constrained from leaving the system as heat. No heat implies no cooling and reduced energy consumption.

Our digital infrastructure has arrived at a historic crossroads, going forward with the present trajectory would lead to stagnation and spiralling cost due to physics. This decade will be defined by the technical challenges of reversible computing where the physics has no upper limit.
