The script for "Predestination" (2014) is identical to 2008 4chan creepypasta

I heard about the movie "Predestination" on this subreddit recently and was intrigued, so I went to watch it, and about 30 minutes in I realized it seemed very familiar. After some googling I found this, which was exactly what I looking for and what was causing my déjà vu. Its a 2008 creepypasta from 4chan that is the exact same plot as this movie. I just felt like this was interesting and needed to be pointed out for anyone who has seen the movie, read the story, or both.
