AI will definitely impact content creation, everything from music to art to cinema, to video games.
Right now, there supposedly exists AI that can mimic a voice based on only a few seconds of "listening" to a person's speech. So if you are making an animated film, you would no longer need to hire voice actors for dozens -or hundreds- of hours of reading lines. You might only need them for a few hours. The cost savings would be significant.
And, once you have a large enough database of live recordings, how long would it take to program an AI to create new and unique voices and speech patterns? How long before voice actors would be unnecessary?
And with graphics engines like Unreal 5.2, you are close to having photorealistic video footage that renders in real-time, with the ability to apply rotoscoped facial animation to any characters you create. Again, build a library of faces and use AI to create unique faces from that library. Now you don't need actors at all.
Do the same with music or even scriptwriting. How long before movie studios produce endless streams of content with little to no input from humans, allowing them to produce "entertainment" with almost no up-front cost?
