On their own? Nothing.

But Graphene doesn’t mean anything to the general public. People aren’t buying “an iOS device”, they are buying iPhones. People aren’t buying “an Android phone”, they are buying “a Samsung/Galaxy” or a “Pixel”.

Mind you, when I say people, I mean the general population. Not those actually interested in these subjects.

My point is: people don’t care about these specifics, people care about having a frictionless experience (or as close to frictionless as possible). Having to explain what Graphene even is is friction enough for most people to not even bother listening to your explanation.
