xD well I dunno what happened, but I dont believe all knowledge was lost.. it's slowly being recovered in the form of relics and artifacts.

Also..I dont think it'd render advancement useless...but the idea is to excercise proportional wisdom. If you advance and you dont get wiser while doing so, stuff like building superpowerful weapons of mass destruction tends to happen.. and it's really only a matter of time before you committ some collosal irreversible f***up which unintentionally cleans the slate of human civilization.

The idea to me is to advance, and become wiser,..and then you wont mess it all up, as has probably been done a few times, and is about to be done again by us.
