This is going to be huge. I never expected this step to be coming very soon as I thought this is the phase where we are understanding A.I and finding ways to make a controlled A.I system. I don't believe we have achieved that confidence but I think I am cent percent wrong. We must be too far than that which should be the confidence behind thinking this concept.
I don't understand why this post is downvoted. You have a perfect example of an AI algorithm parsing text, determining feeling and responding with what it thinks are relevant words. It couldn't be more on-topic than this. AI is participating in HN discussions.
