Aren't the loops the wrong way round in the diagram. The tightest loop is the inference loop, then the tool loop and then human loop?

I think of them from the outside in, so that's why I illustrated it that way.

		Fascinating. I think it's the first time I've heard it put that way. For me it's more intuitive the other way around, as the "outer" loops increase in complexity (and can have additional separate loops running inside them). It also makes sense because you can always add more (meta) loops that way.

You are absolutely correct. It's an i18n/l10n issue. They spin in the opposite direction in the other hemisphere.
