41% of Long LinkedIn Posts Are Fully AI-Written, and the Robots Are Talking to Nobody

A detection company called Pangram measured the slop people actually see instead of the slop just sitting on dead servers, and the feeds are drowning. As much as 41 percent of longform written content seen by users on LinkedIn is likely to be fully AI-generated and roughly a third of longer posts on X are AI-generated, while roughly one-in-ten longer Reddit and Substack posts are AI. The method matters here, because the company analyzed roughly a million posts that its users organically scroll through across LinkedIn, Medium, X, Reddit, and Substack over a two-month period. LinkedIn earned its crown honestly, since it had for years built AI writing tools into its platform meaning that it has been incredibly easy to post AI-generated content on the platform. Half your professional network is now a language model congratulating another language model on a humbling career milestone. 404 Media on the Pangram browsing data
