The first large computer was introduced in my childhood; it was called Univac, made by a company which produced vacuum tubes like those used in old radio and electronic circuitry. It was about the size of a couple of Ford Econoline vans beside each other; IBM came out with a better version with more ability, and faster processing, using punch cards to feed the data in. It took up almost half a city block in size. and now, a medium grade laptop has a hundred times the capacity, over a hundred times the speed of processing, and costs less than one thousandth the price. the moral to this:When the Japanese introduce those smooth skinned rubber sex robots, don't buy one in the first couple of years. By the time you need Viagra and heart meds, they will be cheaper than a Colombian hooker, and feel so much better than the old blowup doll handed down from your Grandpa to your Dad and then down to you, in those special rituals at the Masonic lodge.
