It is intriguing to observe how both Machine Intelligence and Human Intelligence are incomplete in their own unique ways.
On one side there is the machine Intelligence (or Artificial Intelligence) that operates in a clearly defined fashion. This clearly defined fashion has been dreamed up by us. And perhaps this ‘clearly defined and predictable fashion’, in which the machine intelligence operates, is what makes us say that AI is not there yet. We feel that it is not sophisticated enough to stand on its own feet and take relevant decisions in uncertain context. When the machine processes something for us, we know what exactly it is doing i.e. the sequence of steps that are helping the machine to process – be it weather reports, translating a document into another language or a move in the game of chess, but the machine itself does not know what is the meaning of that what it is doing. 
On the other hand we have the human intelligence - which we, as a species, are very proud of! While doing something we not only process it accurately mentally but we actually consciously know what is that we are doing. Without flinching one bit, we can adapt in different situations. As I mentioned in my earlier post Copy Paste this is what sets human intelligence apart from the world of AI.
However it could not be more ironical to observe that we ourselves still do not accurately know how are we intelligent the way we are. In other words, we understand the complete meaning of what we are doing, but we still do not know how our Brain is accomplishing it!
