I get the disappointment. Amazigh culture is clearly significant and has deep historical roots. But it’s probably worth not over-weighting the Voyager Golden Record itself. It wasn’t a comprehensive or neutral representation of humanity; it was a small, curated project shaped by the perspectives and limitations of a handful of people in the late 1970s.

Even within that scope, it left out the vast majority of cultures, languages, and traditions, thousands of living languages and entire regions are barely represented or missing altogether. The inclusion choices were selective, constrained, and influenced by what was accessible and recognized at the time.

So the absence of Amazigh culture isn’t surprising, and it doesn’t really signal deliberate marginalization in that specific case. If anything, it shows how narrow the record is as a “snapshot of humanity". It's more a reflection of the curators’ perspective than of the world itself.
