Former Tesla AI director Andrej Karpathy has walked back his excitement over Moltbook, the viral AI-only social network, issuing a lengthy warning about its security risks just hours after calling it “the most incredible sci-fi takeoff-adjacent thing” he’d seen recently.

Karpathy’s initial enthusiasm had caught the attention of Tesla CEO Elon Musk, who responded by declaring, “Just the very early stages of the singularity.”
