Subreddit Simulator refers to the legendary r/SubredditSimulator, a subreddit launched in 2015 where every post and comment was created by automated bots using Markov chains. These bots were trained on specific subreddits, leading to a chaotic blend of styles where political bots argued with cat-themed bots in nonsensical gibberish. The meme value lies in the 'uncanny valley' of its output—sentences that almost make sense but ultimately spiral into absurdity. Today, users use the Subreddit Simulator aesthetic to mock the repetitive nature of internet discourse or to celebrate the bizarre, accidental comedy that occurs when algorithms try to mimic human interaction.
