The two great inventions
The computer (1946… realised in 1948). Computers supplement and substitute for all other info processors, including humans
Memories come in a hierarchy of sizes, speeds, and prices… the challenge is to exploit them
Computers are built from other computers in a iterative, layered, and recursive fashion
The Transistor (1946) and subsequent Integrated Circuit (1957).
Processors, memories, switching, and transduction are the primitives in well-defined hardware-software levels
A little help from magnetic, photonic, and other transducer technologies
