Mixing can be creative but it very often is not. If you are trying to fit in with a specific genre many of the mixing "rules" will be fixed, whether it be bringing the drums forward, the vocal, the guitar or whatever. There will always be space for individual mixing but in the coming years I think we'll see AI being able to handle much of the task, especially the basic stuff like levels, panning and EQ. And I'm looking forward to that!
AI is in its infancy and it is going to improve very quickly. It can already write songs, complete with lyrics and vocals. Yes, those songs are derivative but so are many of the songs humans write, because we're all influenced by years of listening to music. The difference with AI is that it has listened to pretty much everything. In a few years it will be difficult to identify an AI written song. I'm certain that there are already AI elements in use in the industry.
I'm just glad I'm not trying to make a living at it, because sites like Suno are going to make it very hard for new songwriters to break into the industry.
