Who Owns The Copyright Of AI-generated Content?

The time has come for lawmakers to settle this debate before it's too late. The thumb rule is never to reproduce works of any writer or artist without permission and/or payment of royalty/fees. Here's an example: developers use Y platform to make a phone app, and then sell it in the market for a fee. The debate so far: AI is being used to write articles, news reports; generate works of art, music even. The opposition counterargues that till such time that a machine can think "creatively" on its own, without human intervention, a human being IS responsible for creating the data base.
