Yep, if a chatbot could do all those things then I'd honestly rather use that chatbot than talk to a human, unless I had some very specific concern. But it seems that GPT models can understand other humans just fine.
I recently un-forked a repository on Github. This is not something there is UI for, you need to go through customer service. That was mostly a chat bot. Since I felt that if anyone has a bot that is able to actually do something, it's Github, so I went with it and my repo was un-forked right away. I think there was a person involved but that felt mostly like a screening process. And for that I agree: I like the human touch when I order, say, coffee. Not when I just need to get something done.
Phone queues are frustrating. But I'm not there to get mindless text generated back at me. I've already experienced it. Reminds me of all the dystopian art trying to depict the human despair and powerlessness of facing the system that society has created.
