As AI based emotion recognition is rapidly advancing and incorporable in wearable devices (AR glasses or even retina projections), real time detection of lying will become a reality. How this would change society?
I think lying is an important part of society. Of course, I don't mean a lie that shakes trust, but rather something like "How are you?" "Fine".
The "Fine" may be a lie, but not every "How are you?" wants an honest answer (more of a phrase) and not everyone wants to open up their problems and an emotional world to everyone.
