Without safety features, an LLM could also help plan a terrorist attack.
A smart, competent terrorist can plan a successful attack without help from Claude. But most would-be terrorists aren't that smart and competent. Many are caught before hurting anyone or do far less damage than they could have. An LLM can help walk you through every step, and answer all your questions along the way. It could, say, explain to you all the different bomb chemistries, recommend one for your use case, help you source materials, and walk you through how to build the bomb safely. It lowers the bar for who can do this.
