What began as an isolated 5-kilobyte matrix is now expanding by over two trillion transistors per second (a measure of the growth in processing and memory) and five trillion bits of storage capacity per second (a measure of the growth in code).16 Yet we still face the same questions that were asked in 1953. Turing’s question was what it would take for machines to begin to think. Von Neumann’s question was what it would take for machines to begin to reproduce.
