Quantum thinking and speaking

Here is a link to an article from New Scientist that tries to relate the mathematics of the quantum world to human interaction.  An explanation, in effect, of our fuzzy way of going about things.  It casts an interesting light on the puzzle I have as a playwright - the sheer impossibility of capturing or reproducing human speech in all its wide, broken rambling, halting form but while still managing to convey some sort of meaning.  I have never managed to find a way of notating speech in anything resembling a realistic, believable way.  Pinter arguably came the closest to making this work but he still had to resort to a rather mannered "pinteresque" approach.  Of course, a playwright does not necessarily want to reproduce everyday speech exactly.  It would be massively tedious to the audience, and probably totally incomprehensible but there is an inbuilt urge towards getting closer than we have managed up to now.  The reason being that we may wish to describe in our plays a more realistic way of describing the trains of thought of our characters.  And those are inexorably linked to the way they speak.  I need to read the article several more times to get some deeper insight but I like its drift.
