An interesting topic to ponder. My personal belief is that computers will only surpass human intelligence or have true AI when one can pass the "I know what I know test"
An example: You ask me these questions
1)What is your birthday (July 4)
2)What is your daughter's birthday (July 18)
3)What is Abe Lincoln's birthday (Let me think about that. I learned that in Elem school. Oh yeah Feb 12)
4)What is Erik's birthday (I haven't a clue)
In the first 2 questions, I should know and readily respond. In the 3rd, I do know and I KNOW I know, but might need to cogitate to answer. For the 4th question, I don't know and I KNOW I don't know.
A computer does not have that quality. It does NOT know what it knows. It only can respond by checking its data sources and then respond with the fact the "information is not available"
Just my thoughts
