It's a pretty absurd claim to say that learning Suno is no different than learning a musical instrument. My 8 year old nephew was cranking out "songs" in Suno within an hour of being introduced to it. Reminds me of when parents were super impressed that their 3-year old could use an iPad.
Generative tools (visual, auditory, etc.) can serve as powerful tools of augmentation for existing creators. For example, you've put together a song (melody/harmony) and you'd like to have AI fill out a simple percussive section to enrich everything.
However with a translation as vast as "text" -> to -> "music" in terms of medium - you can't really insert much of yourself into a brand new piece outside of the lyrics though I'd wager 99% of Suno users are too lazy to even do that themselves. I suppose you can act as a curator reviewing hundreds of generated pieces but that's a very different thing.
I always get a little confused when I hear non-musicians say that something like Suno is empowering when all they did was type in, "A Contrapuntal hurdy-gurdy fugue with a backing drum track performed by a man who swallowed too many turquoise beads doing the truffle shuffle while a choir gives each other inappropriate friendly tickles".
