Yeah, but that's driven by familiarity not understanding. A median western marketing executive has no better understanding of electrodynamics than your amazonian tribeswoman, yet isn't surprised by the radio in his phone.
Maybe it's also worth clarifying that familiarity doesn't mean or lead to understanding. Sometimes quite the opposite (hint hint: newer generation using smartphones, social networks, etc without understanding them at all and then some from older generations remarking how they can be dangerous and upsetting).
