@29d67b21 OK, try a different one.  In the bash case, someone sits down and writes code to perform a task.  In the AI case, it's a training - there's no definition, the training process has inferred the mapping. 

 @29d67b21 But you have no complete definition of the tests in the AI case; the fact you don't know the relationship between pixel input and 'it's a person' is why it's inferred isn't it?
