A birth mark?! --- Its a really good question whether AI will ever be able to decode the unsaid given how many variables are involved and how context dependent these are. Its even difficult for many humans to do so, people on the Autistic spectrum especially as they do not have a good feeling for the minds of others. And all of us make mistakes when we aren't familiar enough with some of the variables involved. Perhaps in the future, when AI intelligence is nearly indistinguishable from human intelligence in most regards, implicit communication will be the 'tell' which will help us distinguish between man and machines!
