There are drawbacks to being a skilled (trained/practiced) musician. You specialize in one instrument, and tend to have your creativity guided by its strengths/weaknesses.
I think that soon, some very accomplished musicians will learn to leverage tools like Suno, but they aren't in the majority yet. We're still in the "vibe-coding" phase of AI music generation.
We saw this happen with CG. When it started, engineers did most of the creating, and we got less-than-stellar results[0].
Then, CG became its own community and vocation, and true artists started to dominate.
Some of the CG art that I see nowadays, is every bit as impressive as the Great Masters.
We'll see that, when AI music generation comes into its own. It's not there, yet.
