We use AI assisted coding to be more productive or to do boring stuff. If the 'making the music' part is what you are getting away from, why make music? You're basically a shitty 'producer' (decent producers are amazing at those boring parts you are skipping and can fill out a track without hitting up a robot) at that point.
Music is math. Art is patterns. Like how we're using AI to iterate through design and code, musicians could use it for generating musical patterns including chords, harmonies, melodies, and rhythms. In theory, it can pull up and manipulate instruments and effects based on description rather than rifling through file names and parameters (i.e. the boring stuff).
Most success as a musician stems from developing a unique style, having a unique timbre, and/or writing creative lyrics. Whether a coder, designer, artist, or musician, the best creatives start by practicing the patterns of those who came before. But most will never stand out and just follow existing patterns.
AI is nothing more than mixing together existing patterns, so it's not necessarily bad. Some people just want to play around and get a result. Others will want to learn from it to find their own thing. Either way works.
With art and AI, people seem to enjoy the part where they say they made something and get credit for it, but didn’t actually have to bother. People used to find art of people on the internet and claim it as their own, now an AI can statistically generate it for you and it maybe feels a bit less icky. Though I have to agree it all seems sort of pointless, like buying trophies for sports you didn’t play.
