What are we talking about? Philosophically yes. Factually, no. In the context of a system innovation could be switching from one form that renders in 1 second to another that renders in 50ms. Stability isn't part of that equation.

Is this switching risk-free? Consider all these ancient computer devices that run high-stakes equipment for years and decades without change. An RPi could replace an ancient PDP-11, cost a fraction, consume a fraction of energy, be faster, etc. But it also may introduce new and unknown failure modes.
