I never said knowledge will disappear. I said the sustained application of that knowledge will successively become more and more difficult that society will eventually lose such access to such technology due to a finite number of resources. Take modern rocketry as an example. The equations and the science it took to get to the moon were already 300 years old before the Americans went there. The science isn't going anywhere, but once say sending a current down a wire becomes as prohibitively expensive as putting one-pound payload in low-earth orbit due to a lack of viable industrial minerals, basic electronics would quickly become a thing of the past.

Yeah I misunderstood.
