Someday it might be the case that your offhanded grunt helps an automated assistant interact more successfully with grumpy people. Decades or centuries from now, when the global or interplanetary cloud algorithms for language translation are so refined that there's only very occasional room for improvement, your grunt might turn out to be worth a million dollars. It might sound strange today, but imagine how strange it would sound to a hunter-gatherer from thirty thousand years ago that a star's grunt on a movie screen would be worth a million dollars today.
