Good. Every time we forget the old world, we reinvent it better
Historically that has not been the case for most of human history. As odd as it might seem, in general the rediscovery of the accomplishments ancient world has been a great driver towards progress. The periods when the accomplishments of the past were lost and fully forgotten were the sorts of times people call Dark Ages.
Obviously we can’t be sure how the current era will be viewed from the far future, but your comment made me realize that the current situation has similarities to that dark age.
(or the ones where the "old city" was destroyed in brutal urban warfare)
