There is some truth to it. I personally don't read most blog post, including medium. The quality of content is IMO proportional to the author's experience and their effort in producing the content. On medium/Twitter/whatever blogging platform it is just too easy to create crap, crap that aims to "build up audience". Flood them with AI generated content might hint reader to go somewhere else, hopefully somewhere with more depth.

Book is where I find the most value.

I think the argument is, AI generated content is less crappy crap than the current crop.

They’ve tried to attract high-quality human work for a while, and it doesn’t seem to have worked for them. Might as well try something new instead of digging in.

Much like /r/SubredditSimulator, at this point, the robotic crap will stink less than organic feces.
