Don’t buy the “knowledge disappears because nobody needs it” premise.
We still have people learning Latin, blacksmithing and ham radio. Humans preserve useless knowledge obsessively, often because it is useless. As geohot put it, there will always be some guy digging the hole himself.

This is too romantic.
Yes, there will always be a guy learning Latin or hand coding assably. That is not the same thing as a civilization retaining technical knowledge.
FOGBANK is the canonical counterexample: the US had made a nuclear weapons material before, still had the weapons, still had the labs, still had the budget, and still had to rediscover parts of the process because the tacit manufacturing knowledge had leaked away.
