Technology is a bit like clothing. Hundreds of thousands of years ago, a single item of clothing (a well-tailored pelt or loincloth) would probably suffice. Clothing did one thing, provide cover. Tech has become no different. Tens of years ago, a PC was our primary, if not sole, piece of "technology." But now we have smartphones, and tablets, and e-book readers, and Internet TV boxes and gaming consoles.
