I'm not worried about AI replacing content creators. If anything, it will make the low effort bot generated content all platforms have been filled with for years now at least somewhat more interesting.

What I'll be annoyed by is the amount of it that will exist, which will make finding high quality content made by humans much more difficult. Audio and video content will become spam infested as text has been on the web for decades now. We'll be flooded by SEO'd to hell garbage, propaganda and deep fakes, and curation will be crucial to find the signal within the noise. I guess we'll come up with new AIs and new platforms to help us with that as well.

I can hardly wait. /s
