I'm surprised there isn't more discussion about hype cycles and the poor efficacy of "AI" here. Sentiment analysis (find the uncivil words) is a trivial solved problem in 2017, and is many, many orders of magnitude less computationally complex than the semantic intelligence problem that would have to be solved in order for robots to be useful here.
