Is this the moment when the word "writing" started to change shape and become something else.
"Huh?" I hear you say. Well, just think how the meaning of printing (and printers) has slowly changed in recent years - how it seems to now be about 3-dimensional accretion-building... though, you know, printing has always been three-dimensional - not being pedantic here, you know; just pointing out how perception shapes language and vice versa - ink has depth, right?; it's just that we've never bothered to think about it that much; we think of paper as two-dimensional and the words written - printed - on them as being 'flat'. The brain has no need to consider depth where the written word is concerned; physical representations of language lack 'volume' for us; they are not objects - or, rather, we've never needed to consider them in that way before.
Words are 'flat'.
But printers (in the contemporary context of the word) (re-)create things that we can recognise / acknowledge as being objects as we traditionally understand them, so the process seems to suddenly telescope out into the physical world - it gains depth - printing occupies space in a way it never did before and so printers are now referred to as "three-dimensional" though, in reality, they always have been; there's just been a perceptual shift.
So, now the meaning of "Writing" is also starting to drift towards becoming something new that our children / grandchildren will accept as their norm.
You can now 'write' lipid-membranes onto graphene layers. And, by inversion-extrapolation, at some point we'll also be able to 'write' on living cell surfaces using graphene or molecular 'inks' that confer new properties on those cells.
Meaning just shifted there. Did you feel it? The world just changed a little, but no one really noticed. Well, not yet anyway.
'Writing'. (In commas, for now).
