I am not totally sure about this. I think that AI writing is just a progression of current trends. Many things have made writing easier and lower cost - printing press, typewriters, word processors, grammer/spell checkers, electronic distribution.

This is just a continuation. It does tend to mean there is less effort to produce the output and thus there is a value degradation, but this has been true all along this technology trend.

I don't think we should be a purist as to how writing is produced.
