The other thing is that on modern platforms, decomplied code can and will be ludicrously complex and probably rely on several levels’ worth of abstraction layers, external libraries, API’s, and sandboxes provided by the OS or whatever other platform it’s meant to run on. Outside of microcontrollers and some embedded applications, the days are long gone where you just have relatively simple machine code running directly on the bare metal of the computer’s processor and unprotected memory.
