Makes me wonder if there is ever any non-toy usage of AI sentiment analysis. People (managers, customers, marketing, etc) think is the hottest thing since sliced bread, but every time I've looked at it, the results are meaningless noise, like in the myriad of examples in the comments here. It's a cool bullet point in the slide deck, and it gives you some metrics to graph on dashboards, but I'm unconvinced that it means anything.
