Model-Dependent Realism: Is This the Worldview of Software Engineering?

Excerpt: S. Hawking and L. Mlodinow proposed Model-Dependent Realism as a worldview for physical theory or science. It is quite similar to B. C. Smith's opinion in 1985.
I just read an idea by Stephen Hawking and Leonard Mlodinow, called Model-Dependent Realism:
“the idea that a physical theory or world picture is a model (generally of a mathematical nature) and a set of rules that connect the elements of the model to observations.”
This statement is rather matching with my thoughts, almost in each word. (Of course, we perhaps may ignore the “physical” and take some extension for “observations”)
This reminded me of the Smith’s opinion: (see the Figure 1 below)
“You are to imagine a description, program, computer system (or even a thought – they are all similar in this regard) in the left hand box, and the very real world in the right. Mediating between the two is the inevitable model, serving as an idealized or preconceptualized simulacrum of the world, in terms of which the description or program or whatever can be understood.”
Figure 1: Computers, Models, and the Embedding World (Smith 1985)
Is this the apposite worldview for software or computing? Whatever, Smith have pointed out some key relationships for models with computers, and with the real world — of course, it still needs more — but it seems have been somewhat lost or ignored, isn’t it?

 The phrase “model-dependent realism” appears to have been coined by Stephen Hawking and Leonard Mlodinow in their 2010 bookThe Grand Design. (quoted from: “What Is Model-Dependent Realism?” by Andrew Zimmerman Jones, About.com Guide)
