Paul Graham shared an observation about changes on the Twitter platform. He noted that Twitter now classifies a large number of AI-generated replies as probable spam. Specifically on a recent tweet he made 34 of the 59 replies were hidden under this category. Graham presumes that AI generation was the main reason for this action. He further states that this situation is likely to worsen over time. As a result he anticipates that from this point onward the majority of replies to tweets will end up hidden from users.
