Well, the compiler would not process right your normal way of speaking, because the normal way of speaking requires modelling of the speaker for interpretation.

An image from the camera can mean a multitude of things. It could be an image of a cat, or a dog. An image is never literally a cat or a dog, of course. To tell apart cats and dogs with good fidelity, one has to model the processes producing the image, and classify those based on some part of the model - the animal - the data of interest is a property of the process which produced the input. Natural processing of the normal manner of speaking of language is done using same general mechanisms - one has to take in the data and model the process producing the data, to obtain properties of the process which would be actually meaningful, and since humans all have this ability, the natural language does not - in normal manner of speaking - have any defined literal meaning that is naturally separate from some subtle meaning or intent.
