Lehman's 2nd (increasing complexity) law addresses this. He defines an E-type system as one which is embedded in the "real world" and thus both influences and is influenced by it, and then claims that:

"as an E-type system evolves, its complexity increases unless work is done to maintain or reduce it" [1]
