What I'm referring here isn't creating plugins with AI.
Dan suggested this.
Yes, I believe this will be the intermediate stage. Where AI can help anyone make the tools they need use to create their music.
The stage after is to simply describe what kind of music (the specific parts) you want to make. That will remove the need for plugins.
Instead of downloading a bunch of different reverb plugins, you just tell the DAW exactly what type of reverb you want and it will create a custom one. Then if you make a really cool reverb you can share it with other people, heck even sell it if it's good enough. Wait... we've come full circle to selling plugins at this point! 
Parallel to this is also likely the stage where the end-user just describes what music they want o listen to and it's generated on the fly.
Ahh.. but this is all supposition. Nobody really knows where this will all go.
It might all collapse in on itself and turn out to be a big disappointment. Or it might wipe out humanity entirely.
