For the past few years, a conspiracy theory called "Dead Internet theory" has picked up speed as large language models (LLMs) like ChatGPT increasingly generate text and even social media interactions found online. The theory says that most social Internet activity today is artificial and designed to manipulate humans for engagement.

On Monday, software developer Michael Sayman launched a new AI-populated social network app called SocialAI that feels like it's bringing that conspiracy theory to life, allowing users to interact solely with AI chatbots instead of other humans. It's available on the iPhone app store, but so far, it's picking up pointed criticism.
