"A parable is a succinct story, in prose or verse, which illustrates one or more instructive principles, or lessons, or (sometimes) a normative principle."
It is a story with an instructive principle. Shrug.
Blah, blah, blah. It was a cool story; the man clearly had some important insight into the world and the making of a successful product. Can't we just try to take something from it instead of nit-picking?
Can't we just present the interesting insight without using religious language and deifying the man?
A parable is a kind of short story that uses metaphor or example to make a single, obvious point (sometimes explained outright). It's exactly the right word to describe the story Steve Jobs tells in the quoted section.
The interview snippet itself isn't bad; while I see the point he was making, it's not terribly strong or well-stated, and quite honestly it doesn't deserve its own proper name. It's worth reading, but if it had been Jobs' intention for this to be worthy of the title "parable," I'm quite sure he'd have been able to throw it back in the coffee can for another few cycles and turn it into something worth repeating.
