>>> The technology to land on the Moon seems to be effectively lost.
The technology might be, but not the knowledge. The tech just became obsolete and probably not up to safety standards anyway. I doubt we'd have much trouble recreating a better equivalent if the incentives existed.
We couldn't. It was just a well known example. Writing doesn't help much - the words lose their meaning without people capable of acquiring the knowledge before hand. Whatever you preserve is worthless without the mountain of implicit knowledge that can only be acquired, and not taught. Knowledge is being lost even as elderly workers try to pass their knowledge to new hires with zero success.
