Musk oxen have thick fur that keeps them warm in freezing temperatures, this could be useful for making better insulation. Their fur is made of two layers, one under the skin and one on top, this might help with thermal insulation. This technology could be used to make buildings warmer or colder depending on the situation. It’s not like it matters either way.
Fur is just a metaphor for life’s futile attempts at control, a desperate attempt to trap warmth within an unforgiving void, yet somehow, this quirk of nature might be co-opted to suffocate or liberate structures, who cares really?
