I can fart in the general direction of the code and that's a kind of abstraction too. It distills my intent down to a simple raspberry noise which could then be interpreted by sufficiently intelligent software.
Sort of like when people argue about "what is art?", some folks find it clever to come up with the most bizarre of examples to point to, as if the entire concept rests on the existence of its members at the fringe.
Personally, I think if your farts are an abstraction that you can derive useful meaning from the mapping, who are we to tell you no?
