It’d be like asking years hence, the Americans had been to the moon, why wasn’t anyone else curious about the moon, why hadn’t others put people on the moon?
I'm asking that question now. Even for Americans, the majority never had a moon landing in their lifetime. And with each passing day, it gets a little bit easier to believe the whole thing was a hoax. Hollywood can deepfake better moon footage than the historical record these days.
Since the resources coming from the North Atlantic were not that valuable, the knowledge of the lands and culture there stayed with the people who worked it.
"The high value that medieval Europe placed on walrus ivory would have provided plenty of incentive to pursue it in Greenland. Craftsmen used ivory in luxury ornaments and apparel, and in objects like the famous Lewis chess set, discovered in Scotland in 1831.
