At least we think about it. The miracle material, graphene, has properties that could potentially cause problems when breathed in [0]. So at least we know what to look for and can mitigate.

That said, who knows what other material might come about that causes problems 40 years later in a different way. We will learn when it comes but at least we’re starting to be more aware of potential problems.
