What does casting biochem in the metaphor of CS abstractions, in this example, clarify? What does it elucidate? What further predictions does it allow us to make about either subject of the metaphor? Can those predictions be tested? Do they make sense enough for that to be a meaningful question?

Show me how this isn't a more confusing than useful explanation, even for the bright ten-year-old or so at whose level it appears to be pitched, and I'll grant it may have some value.
