Pre-Christian societies (Greeks) had knowledge of steam power, (Babylonians?) electricity (old electroplating plating batteries found in ruins) and that the Earth was round and not the center of the universe. Most of this was lost in the rise of Western civilization and the Dark Ages. Does it matter that the technology was used primarily as special effects in temples?
If we were to suffer a planetary disaster that killed off most of our technicians and scientists, modern mass production and microelectronics would become tales of a lost civilization, as no one person could resurrect, for instance, even a small semiconductor fab by himself. Our civilization is only robust when you consider the pool of resources made available by the billions of people out there, and the thousands of different companies competing to make product. A few ill-placed meteor strikes could indeed send us back twenty or thirty years, effectively.
This does not imply that the actual knowledge is lost - just that the know-how to make the knowledge into product is missing. The field-effect transistor was known in the early years of the 20th century as a possibility, to physicists, as was nuclear fission, but until the infrastructure developed to make either viable, they remained dreams.
