This thread talks about the implications of AI content but it is not clear that this has been resolved.
Frustratingly, it looks like editors went out and created artist entries for certain AI computer programs. I do not think these are artists, as they are computer programs. They do have sleek marketing which implies that they are, or even better than humans, and we should be careful not to swallow it.
Here is one for Midjourney: Midjourney - MusicBrainz
Given this thread seems to have become a philosophical discussion, but there is no software artist type (or resolution of whether there should be), this strikes me as slightly unhelpful. To my mind, in this context, we should wait for consensus.
