Elon Musk has acknowledged the need for a comprehensive overhaul of X's algorithm following criticism from Andrej Karpathy, a key figure in AI research and a former Tesla executive. Karpathy, who praised the Claude AI assistant on X, faced backlash from users accusing him of being a promoter. He criticized the platform's algorithm for promoting hostile content to boost engagement, leading him to reduce his activity on X. Musk responded to Karpathy's concerns by agreeing that a complete algorithm overhaul is necessary.
