Many subreddits are simply themed containers of creative writing. With all the media attention the AntiWork subreddit has gotten lately that brings more karma farmers and therefore more fiction. It's an entertaining read, but not likely true.
Its possible that my friend lied or exaggerated the situation, and also possible that the author of the reddit post isn't being completely honest. Personally, I'm inclined to believe the stories are mostly true.
Even at my BigTech job I have seen opportunities were non-technical people were doing highly repetitive work that could be automated if they knew how to code.
