r/ClaudeAI·medium signal

A viral r/ClaudeAI post (359 upvotes, 72 comments) shows Claude's extended thinking feature running for approximately 30 continuous days on a single prompt, ultimately reporting zero findings. The bug highlights the challenges of autonomous AI execution — when thinking time is unconstrained, models can enter loops that consume enormous compute without productive output. Community discussion centers on whether usage-based pricing makes this a $50 or $500 mistake.
