Remember if instant face identifier technology was a sci-fi several years ago? Now, it's real. China uses big data for instant face identifier.

We need to think what AI things that shouldn't made so that no things like in the sci-fi that causes human in a big danger because of high intelligence robots.

AI shouldn't take over the world, as how intellect AI is, AI cannot think as same as human think. Human mind are dynamic, so they can create innovate. High intellect robots like in sci-fi are cannot innovate, their mind are rigid.

So, AI should not take over the world.
