Consider the 256 GB memory iPhone X: Implemented in vacuum tubes in 1957, the transistors in an iPhoneX alone would have:

*cost 150 trillion of today’s dollars: one and a half times today’s global annual product

*taken up a hundred-story square building 300 meters high, and 3 kilometers long and wide

*drawn 150 terawatts of power—30 times the world’s current generating capacity
