It'll lower the barrier of entry (and therefore the quality floor before people feel comfortable sharing something "they made" if they can deflect with an easy "the AI made this" versus "I put XY0 hours into this"), but it'll also empower people who wouldn't otherwise even try to create new things and, presumably, follow their passion to learn and do more.
Here's something you can try to prove it to yourself. Sit down and write a novel. It'll be like squeezing blood out of a rock unless your heart is ready to do it freely. You'll see that if you force yourself through hard work to do it, you'll just end up with something that people will laud as creative due to the execution but it'll lack everything about free-flowing creativity. Good programmers are lazy, so are good creatives, but now I'm just repeating myself.
It's a lot easier squeezing blood out of a heart, especially for the lazy.
