To be honest it smells like AI has become something you just talk about because you have something to sell. It was called web 2.0, then big data, and now it's AI.
I wrote a rant last post (https://news.ycombinator.com/item?id=13599465) about how AI is being oversold. The problem in this case (along with buzzwords like Web 2.0/big data) is that there is some logical advantage to implementing AI/Web 2.0/big data for a business, just not a change-the-world advantage that will not help if everything else is being done incorrectly.
There is a gray area in between the marketing, and the ambiguity is the real danger.
I don't see any danger with AI, I'm optimist that it will introduce great changes.
I'm just bothered by the whole market tendencies, it often sounds like it's appealing to salesmen, meanwhile doing real stuff with machine learning is tough and it is often the realm of research and universities.
