I've been reading about the Voyager Golden Record sent with Voyager 1 and Voyager 2, and I'm really curious about something.

How did scientists conclude that any intelligent extraterrestrial life would actually be able to decode it? I get that they used universal concepts like physics, math, and things like the hydrogen atom and pulsar maps, but isn't that still a big assumption?

Like, what if alien intelligence works in a completely different way or perceives reality differently-would any of this even make sense to them?

Was the record designed with a specific type of "intelligence" in mind, or was it more of a symbolic attempt rather than something expected to be understood?

Curious to hear thoughts, especially from people who know more about the design decisions behind it.
