" Von Neumann saw great promise in a redesign of the ENIAC computer’s memory. He believed there was a way to turn the computer into an “electronic brain” capable of storing not just data and instructions, as was the case with ENIAC, but additional information that would allow the computer to perform a myriad of computational functions on its own. This was called a stored-program computer, and it “broke the distinction between numbers that mean things and numbers that do things,” writes von Neumann’s biographer George Dyson, adding, “Our universe would never be the same.” These “instructions” that von Neumann imagined were the prototype of what the world now knows as software.
