I've had this conversation pretty often. As an artist, I will always be heavily against the usage of AI in the field, just because it trivializes people who have spent years perfecting their craft and honing their skills, as well as takes work that they need away from them. On Chaos, I don't mind it as much because I mean we all use playbys of existing things or something we can easily grab off the internet. If you got a clear idea of the aesthetic you want, and you can't find literally anything that matches it, fine go for it. When it comes to creative writing, there is some leeway, but I have a very biased perspective against it.
I think as a tool sure, use it to make things easier. See a 10000 word post you don't want/have the time to read and have it summarized down to concise and clear points? Go right on ahead - if I want to read the flavor text I will. Want to have a general idea of how to respond to a certain situation, great, use it as a framework. Build upon the framework that it provided you, but embellish it with your flair and touch. I do not think that at any point it should ever overtake the point of writing to begin with. You are here to roleplay, this is a hobby where you get to express your creative writing skills.
If you have reached a point where you use AI to generate your posts entirely, I think you've reached a point where you need to take a step back and remember to find the joy in it. Quality not quantity - this is what most, if not all of us were taught growing up.
Treat it like cooking, you can use it to enhance the flavor of a dish, but it should not overpower everything else and become the main focus of it. You put your time and effort into it is what makes it enjoyable not just for yourself, but to the people you are serving it to. I don't want to be reading some robot slop that lacks soul or depth. Let me pick your brain and enjoy you through the writing you produce please.
