depends on the code, your thinking is quite flawed they can have different inputs I mean change their own "interpretation" they can even learn from before and add more in, you are thinking in terms of code that is "dead" nowadays you can do so much more so much faster. You can program it to swap modules to swap inputs/outputs to iterate and improve to add in new ones and so on. :) Aren't we all just autonomous machines taken out of the universe :)
