Firstly, I'm an old guy but I've enjoyed tech things since I was a kid when taking apart radios

and building Heatkits. I find AI fascinating and not, as many, threatening.
However Biab is so multifaceted that in general it IMHO must be considered within the context of the user. And this is from a guys who loves BiaB but uses a tiny percentage of its capabilities. AI providing a backing track and vocals per request is one thing. Another is sitting at a DAW comping up multiple generations of RT's, MST's and RD's to support
your song. And pitching shift RT's notes to segue as
you like into vocals, tags, etc. And then mixing it all to
your likes.
You and
your hmmmmm ... isn't that based on your experiences, your likes and dislikes, your definitions of feeling and soul? So perhaps you could end up with an AI product some or perhaps many folks like. But would you?
OK I do understand that with the development of ChatGPT, etc., you might be able to talk with AI for hours or days until is understood you and what you want. Oh, wait a minute, I think I read this morning that Bing with incorporated ChatGPT is bombing out after a longish session and even making insulting comments, etc.

Yeah we are on the cusp and so much more is to come. Of course that view often seems to assume no limits or long stalls … all of which have occurred with many other technologies.
