The state of AI right now...?

Apparently there is "a new Michael Crichton novel" coming out in a few days. What that means is that it is a novel that he had done a lot of work on but did not finish, and now James Patterson has completed it and polished it up for him. Good enough for me. I am looking forward to it.

Does anybody here have a strong sense of how close we are to AI being able to just churn out content in the styles of various deceased authors? I bet they can do it already, but I have no idea how good the results are. I'm sure they are improving every day...

I'm just trying to picture a day, sometime soon, when we can literally get an app on our phones that creates works of fiction or nonfiction prose, of any length you want, in the style of Michael Crichton, Dr. Seuss, Isaac Asimov, Ray Bradbury, Philip K. Dick, Shakespeare, Dickens, Thomas Jefferson, etc.
