In the future, my guess is that courts will generally be on the side of artists because of societal pressures, and artists will be able to challenge any image they find and have it sent to yet another ML model that can quickly adjudicate whether the generated image is "too similar" to the artist's style (which would also need to be dissimilar enough from everyone else's style to give a reasonable legal claim in the first place).
Or maybe artists will just give up on trying to monetize the images themselves and focus only on creating physical artifacts, similar to how independent musicians make most of their money nowadays from touring and selling merchandise at shows (plus Patreon). Who knows? It's hard to predict the future when there are such huge fundamental changes that happen so quickly!
