The most extreme situation is concept artists right now. Essentially, the entire profession has lost their jobs in the last year. Or casual artists making drawings for commission - they can't compete with AI and mostly had to stop selling their art. Similar is happening to professional translators - with AI, the translations are close enough to native that nobody needs them anymore.
The book market is getting flooded with AI-crap, so is of course the web. Authors are losing their jobs.
Currently, it seems to be creeping into the music market - not sure if people are going to notice/accept AI-made music. All the fantastic artists creating dubs are starting to go away as well, after all you can just synthesize their voices now.
It's quite sad, all considered.
