Ultimately, the battle against this is a lost one because our own laws on copyright work against us. You can take an existing copyrighted work and make changes to it calling it a derivative work or even a new work inspired by the old work. How much change is needed? Some rather low level is all that is required.
That's the legal side. What are we fighting? AI produced writing already outpaces human only writing.
I see ChatGPT-4 as the smartest person in the room. Whatever topic I want for my next article on Medium, I use ChatGPT-4. I interview it, mostly learning stuff as I interview it, and drive home my point if I still have it in the interview. Then, I ask it to create some appropriate imagery for decoration. Sometimes, with current events, it will do research on the spot. It does the necessary research, understands it, and comments on it as an expert would after having just learned it the second before.
I gave it an 81 page math treatise I had written. In about four seconds after the upload, it was ready to tango with me on its content.
It's astonishing what it can do. You can't fight or contain this power. It's already deluging society with its vast output.
