"[...] more capable than human intelligence [...]"
I just can't understand all this nonsense some high profile people are talking about regarding AI these days. We're so far away from "real" AI today, that it's not even funny. While there has been great progress in machine learning in the last 2-3 decades - recent results pushing results more to the spotlight -, what we have are certain specific tasks where we have good results for (pattern/object/image recognition, games, etc.) but we have no intelligence in any sense of the word. Every working architecture that we have today is targeted and extensively trained for a single, very specific task (e.g., playing go, recognizing scenes and objects, recognizing specific patterns in signals and mimicking them - robotic arms, Google's music composer, etc.), incapable of doing anything else. E.g., an architecture built and trained for classifying and recognizing certain images and objects can't do anything with audio signals, radar signals, a go playing "AI" can't play chess, etc. No generalization, no transfer of gained experience for application to other tasks, and no real high level understanding and reasoning about anything. And let's not even start about chatbots.
I could go on with this, but my point is, talking about AI being more than humans, taking over, etc. is still very much sci-fi territory.
