Walking through a department store electronics department, i catch a fragment of conversation; some old couple talking to the white-shirt-and blue-tie sales kid right  by the display of SatNav and GPS systems.

"It knows where you are.." he's saying.

"Yes, it knows where you are.." they are saying in reply, like an out-of-synch stereo, "But do you have to know your destination..."

I know that these kinds of sales kids have a bad rep for not knowing much. But this question and its implications might well defy the best of us.

Also:

Their voices weaving in and out of each other like an out of synch stereo.

Their voices sounding less like conversation and more like the early stages of a Steve Reich tape recorder experiment from the 1970's.

Yes. Yes.
It Knows. Knows. Where you. Yes. Where you are. It knows.
But do you? OK? Yes. But do you. Really. Do you have to know your destination?
Do you have to? Ahh. KNow where you're going? Do you need to know that?
Is it necessary to know the destination? Because. That's what we were wondering. Otherwise. That's what we wanted to know.

[Really liking these two, even though I only caught this tiny fragment of them.. feels like a Dickensian shtick one could work with. The doubled voice, the binary, the weaving, repetition. A hideous symbiotic creature.]
