Can AI really be created ?

Question

if yes what will happen to job market, militery, stock market & world.

Answer 1

AI in virtual world is already been created, but has not reach perfection yet(or what the guys deem as perfection) , we also have seen them appearing in reality too, but right now they don't affect much.
But to answer your question = Yes, they can be created. What will happen? Some jobs will change, most rewarding job will most likely be involved with creating of AI, it most likely will destroy more jobs for humans rather than creating them.

Answer 2

The question is not if but when. And I believe, very soon. However the future in this regard is very unpredictable. One thing is for sure AI will be the biggest turning point in the history of mankind.
