I find those kinds of chatbots useful, but those aren't the ones I encounter 90% of the time. Most of the time, it's a chatbot that summarizes the help articles I just read, giving faulty interpretations of the source material, that then goes on to never direct me to a real person unless I tell it multiple times that the articles it's paraphrasing aren't helping. (and sometimes, they have no live support at all, and only an LLM + support articles)
