Will this be helpful to terrorist groups, as they try to get current and future open-weights LLMs to help them create better and more devastating weapons of all kinds?
Take this tool. Feed it a ton of biology/chemistry/engineering/psychology books.
Than ask it to seek vulnerabilities in modern technologies and systems.
It will. Water pipes, sugar, and fertilizer can be used to produce missiles. A kitchen knife can be used to commit a murder. Or a brick can be used to smash someone's head. A tree you plant can be cut and used to construct a club, or a gallows.
Everything can be turned into a weapon of murder if there's motivation. The motivation is key, not the tool.
