摘要

New technology is sometimes old technology, resurrected because better technology of materials or manufacture is available that was not there in years past. Examples of this phenomenon are illustrated with four supposedly modern innovations that actually were sold decades ago.

机译：新技术有时是旧技术，但由于已有更好的材料或制造技术可供使用，因此已经复活。几十年前实际上售出的四个所谓的现代创新说明了这种现象的例子。
