Similar experience, I try so hard to make AI useful, and there are some decent spots here and there. Overall though I see the fundamental problem being that people need information. Language isn't strictly information, and the LLMs are very good at language, but they aren't great at information. I think anything more than the novelty of "talking" to the AI is very over hyped.
There is some usefulness to be had for sure, but I don't know if the usefulness is there with the non-subsidized models.
