The bot demonstrated very well what this article is about. I don’t know the internals, but I also can’t image the bot was using the best and most expensive ways of doing analysis.
It was pretty bad at “getting the point” even when it was obvious, a better system should be able to do so. Sometimes the point is more difficult to discern and there has to be some judgement, you can see this in comments sometimes where people discuss what “the point” was and not just the data. I imagine an AI would have some difficulty determining what is worth summarizing in these situations especially.
