About your work being inevitably stolen, yeah, sadly it will happen, especially with how generative AI is trained. that's why is concerning that the author itself of a project would use AI as a filter in the first place.
But is good that you are public about this and still prefer the feedback from people, but that just made me question why using AI in the first place if you have the support of others? Maybe is because of how tired i am with all of this that the minimal mention of use of AI sets the alarms, but if i worked on a project and have the option of using AI as just a filter to improve said project, i wouldn't use it either way, but that's my opinion on the matter.
I think things are more clearer now, sorry if i didn't express me well enough, English is not my mother language.
