I also thing we just need to find use cases where it is working.

While it will not solve everything, it did solve some things. Like you have found, I have used it for generating simple artwork for internal documents, that would never get design funding (even if it would I would have spent much more time dealing with designer), rewriting sentences so it sounds better, grammar check, quick search engine, enciclopedia, copywriting some non important texts…

I would pay few bucks per month if it wasn’t free. I gave it to grammarly and barely use it.

So I guess next step is just reducing cost of running those models, which is not that hard as we can see by open source space.
