This is starting to get pretty circular. The AI was trained on copyrighted data, so we can make a hypothesis that it would not exist - or would exist in a diminished state - without the copyright infringement. Now, the AI is being used to flood AI bookstores with cheaply produced books, many of which are bad, but are still competing against human authors.
The benefits are not clear: why should an "author" who doesn't want to bother writing a book of their own get to steal the words of people who aren't lazy slackers?
It's as much stealing as piracy is stealing, ie none at all. If you disagree, you and I (along with probably many others in this thread) have a fundamental axiomatic incompatibility that no amount of discussion can resolve.
