Almost no human activity in music is fiddling bits, everything has its place. Pretty sure there are not that many points in music where your role can be trivial. Mastering engineer is somewhat replaced by good music production software and his craft became more approachable to the artist who's not familiar with mastering but can now do it easily due to software.

I do not know if mastering engineers who worked with analog equipment started complaining about losing jobs to digital programs, making their experience obsolete. Did they? I don't think any AI product will be able to separate itself from the human will. Anything we humans do is by humans for humans and all of these places where software would steal our music experience is just hard for me to imagine.
