CAD (Computer Aided Design), which is a broad term encompassing many things and generally speaking, has been nothing short of a revolutionary step in human technological progress, and it allows for the relatively easy repetition amd modification of a successful design.
When applied to IC’s and circuit boards, it, along with CAM (Computer Aided Manufacturing), again a very broad term covering miraculous advancements in precision and productivity of our ability to mass produce extremely complex things, have resulted in formerly inconcievable levels of communication and information sharing made possible by vast arrays of tiny machines capable of billions of “for-next” loops and magnificent volumes of binary calculations which can be programmed to execute functions that aid humans to alter their own perceptions of the very universe and planet that birthed their existence.
