What is your opinion on AI arts?

I have been using NovelAI for the last months now (I used it a lot to generate pictures of Sumireko), and I stopped because of some reason. What about your opinions about AI arts? 

using for personal reason is understandable. but using for commercial is unacceptable. idk man Ai is fun to use or play with and i think we should keep it that way. in my opinion
