[MCU] Why didn't Asgard rebuild to some modicum of its former glory in the 5 years since coming to Earth - was there no one left who knew the intricacies of things like Soul Forges, anti-grav chariots, and the Rainbow Bridge?

First of all: We don't know if the materials needed to build these even exist on Earth, let alone in Norway.

Secondly: The Asgardians are still recovering from the destruction of Asgard and the attack by Thanos, so they prioritize building shelter and creating supply routes over unnecessary pomp.
