"building with material" implies that material cannot be reused, but code can be copied for effectively zero cost, so it isn't like building, so the comparison to inventing and build equipment on the fly doesn't work.

I think we humans find it hard to accept when something is completely new, when there's no analogy for it, because that's how our brains like to think. But software is just _different_ and it's better to give up on analogy than be misled by it.
