I don't get it. Seems she's saying that since complex systems are often computationally intractable without considerable simplifications, somehow that is bad and physicists should feel bad?
I think it's more a meta-question - do things made b/c Science work because there are universal laws or contextual laws?
In her view quantum mechanics is not the underlying description of reality, but a contextual set of laws that work in specific conditions in the same way classical physics work.
Hence the world is "dappled", the applicable regularities depend on contexts. I don't know if this is true, but it is rather interesting as a metaphysics.
