Humans are perfectly capable of coming up with crimes, but in good news, they’re bad at planning crimes that won’t get caught.

It’s not one of the biggest things I’d worry about in the world (in particular, “dumb enough to need a chat bot’s help, but smart enough to get a chat bot’s help” might be a small group), but putting safeguards in place to prevent chatbots from being crime coaches seems like a good thing to try.

Edit: probably even more important, as far as the actual reason it exists, is that it’s a PR thing. Regardless of the actual harm, “the chatbot told me how to make meth” looks bad.
