These are tools. Don't think of them as replacements, they aren't. But as tools that will help us be creative. As smart as these apps seem, they will still need a human to decide where and how to use them. They won't replace us but we need to adapt to a new reality.
I hear this a lot (in relation to various jobs) and I still don't get it. Yes, it is a tool. Yes, if it can, it will replace humans. That's the whole point.
For some reason people tend to think that these tools/AI/ML systems will never be good enough to do their job (or a specific job). This argument can take different forms, sometimes stating that it will just do the boring part of the work (e.g. with programming) or that it will still need human creativity (maybe, but not necessarily and that's not the point) or that it will just replace low level, unskilled or mediocre professionals. And somehow everyone thinks they are not mediocre (i.e. average). But even these assumptions are unfounded. Why would anyone think that these systems will top out below their skill levels? Why would anyone think that they can't become superhuman?
They did in chess, go, I think poker too. Not to mention protein folding. And without much of a hitch between mediocre/good enough and superhuman. Because that difference is just interesting for us, but doesn't necessarily mean that there is huge step, that the system needs to undergo serious development and that it would take a long time. (Like decades or so.) People thought that was the case when AlphaGo beat Fan Hui saying that Lee Sedol was a completely different level. Which, of course, he is. Still, it just took DeepMind half a year to improve alphago to that level.
So yeah, you can be pretty sure that if this track (no pun intended), if this solution is good enough then it will quickly evolve into something that will replace some music creators.
It already is a replacement. You can make a visual novel video game with AI generated character art, backgrounds, music, run your dialogs though AI if you can't write well yourself - and your game will have higher production level than 90% of competition. All those artist you would normally hire or commission the above stuff from are now out of the process if you want. Sure, it's not a particularly high bar, but it's only going to raise from here.
