** simple response:

  Absolute/unchanging clarity of purpose/intent/interaction between various dynamic levels/groups in an ever changing world. (P=NP)

  Unified audience and/or obsolescence? airplane demo[0].
  Obsolescence lot easier to acheive than 100% unified audience. No effort required for obsolescence.

** esoteric response:

  By definition, system(s) approach or systematic approach?  Both provide flexibility ( framework of abstractions ).  Flexibility and absolute determanism are opposing concepts. (NP != P)

 Programming language(s) & related software environments[1] could be seen as a lot of attempts at reconciling flexibility and absolute determanism. (independent of ever changing intrinsics used over years X86/amd, theory CISC/risc/arm/mips and various programming levels[2]) 

  related concepts: NP != P; C language spec[1] (vs. lisp machine vs. lisp running on conventional von von-neuman hardware )

** static/dynamic response:

  Theory/what  - Unused system(s) haven't been introduced to implimentation variations.  

  Practice/how - Used Systematic approach(es) will wind up with intrinsic implimentation variations to resolve mismatches between theory/practice.

  Each will break/degrade when appropriately used.

** snarky:

   Keep it simple, split the difference and use vm/webassembly for testing/debugging. Not very practical, but skip the implimentation & theory can lead to absolute "determinism".  Just move on & don't restart after void/segfault clarity happens.  It's broke. Don't know why -> clarity without understanding underlying implimentation. What's usually missing is the ability to rapidly move on to something else while the spec always produces the same system state.
