In fact, civilisation rises and falls as brainpower rises and falls. There only was a long period of rise recently, but, it's been long over, and we now live off the scraps of what it produced.

But what does your comment have to do with books? There were none in the Bronze Age, nor for many centuries after it.

For example, it was perfectly possible to be born when there was no powered flight at all, and live to see the moon landing. And, while there are all the plans, and everything there was to write down about Saturn V, we can't do it again, as the human potential isn't there anymore. In fact, we can't even fly supersonic anymore.
