Your reply is perfectly valid. Like I mentioned in my entry, I also can't know if someone wrote something or if an AI did it for them. I have already started wondering what is AI and what isn't in some of the new things I've recently read. At this point it's a huge mess.
But I also don't think the comparison fits with the fossil fuels. Don't get me wrong, I'm not a fan of AI in terms of the generative "art" it creates, but some of the benefits of AI are also undeniable. A lot of people are improving themselves because AI can help them do that.
The thing about reaching a turning point is that I think we have already passed it. More and more people are being replaced by AIs regardless of what one furry like me with an obscure visual novel does or says. It's at the scale of the industrial revolution now and we're spectators to all of this unfolding.
As for who wrote the story in my case, that's always going to be me. I can't possibly let someone else do that. Where's the fun in it then?
However, your concern with the authenticity of my work is more than valid as well. But in that case, can anyone even be trusted anymore? I wanted to tackle this subject openly and publicly, but others might not even imagine to do so for fear of being witch-hunted.
Sooner or later though this is going to be something that needs to be talked about in our fandom. It's also obvious that there will be people on both sides of the fence, but I hope we're also all mature enough to have a logical and friendly discussion about this.
