Andrej Karpathy argues X's recommendation algorithm promotes toxicity, and Elon Musk agrees it needs a complete overhaul
Story Overview
Longtime X user Andrej Karpathy publicly flagged a sharp rise in negative, Reddit-style exchanges that he links directly to the recommendation system reinforcing bad behavior through engagement loops, and he has dialed back his own visits and posts as a result; Elon Musk replied that the whole system needs rebuilding from the ground up.

Open Question
Platform tone shifts are hitting engagement habits
Karpathy’s observation centers on how the current ranking logic appears to reward outrage and quick reactions, creating a feedback cycle that feels worse than anything he has seen in nearly twenty years on the site.
Policy Risk
Next steps for the feed stay entirely unspecified
Musk’s call for a complete overhaul comes without any timeline, scope, team ownership, or success measures, leaving users to wonder whether meaningful changes will arrive or when they might appear.
Sentiment
Many users blamed Elon Musk and X's algorithm for driving toxicity, hate, and monetized lies while criticizing Karpathy's remarks as lacking self-awareness.
