A quick note on Weak AI at the foot of the page.

Strong AI aims to create intelligent machines that are indistinguishable from the human mind. But just like a child, the AI machine would have to learn through input and experiences, constantly progressing and advancing its abilities over time.

While AI researchers in both academia and private sectors are invested in the creation of artificial general intelligence (AGI), it only exists today as a theoretical concept versus a tangible reality. 

While some individuals, like Marvin Minsky, have been quoted as being overly optimistic in what we could accomplish in a few decades in the field of AI; others would say that strong AI systems cannot even be developed. 

Until the measures of success, such as intelligence and understanding, are explicitly defined, they are correct in this belief. 

For now, many use the Turing test to evaluate intelligence of an AI system.  more  source

 Weak AI - "The aim is develop theories of human and animal intelligence and then test ... by building working models usually in the form of computer models or robots."
