unfortunately i will accepted that yu are right.....guess AI is in it's initial stage and probably it is having a good enough progress and it is the movie directors who are over-hyping about AI and not the developers. expressing every emmotion of an human being with the help of a code is next to impossible and will surely take a bit of time.....but the future i see we will be having them all the time and all the places protecting us ,guiding us , helping us just like GOD did .....
