Are A Conscious Artificial Intelligence & Smart Robots Possible?

Even the most advanced Artificial intelligence (AI) systems have no real understanding of what they are really doing. The first autonomous cars had fatal accidents when their human drivers were not paying attention as they were programmed to deal with only a set of cars with pre-determined speeds and could not cope up with the complexity of continuous interactions with human drivers they faced (and if they had tested in India, they would have gone crazy with the vehicles coming headlong, or even on the wrong side of the road!). Similarly, a facial recognition system for identifying criminals failed because the input dataset was skewed by police mug-shots in which no-one was smiling. Over the years, AI has become so ubiquitous that we do not even think we are using it. Web Searches, Google Translate, Voice Assistants like Alexa and Siri, fraud alerts from credit-card companies, Amazon recommendations, Spotify playlists, traffic directions, weather forecasts are all taken for granted.
