A talented 17 year old can do quite a bit of damage with nuclear materials: https://en.wikipedia.org/wiki/David_Hahn

I'd personally prefer that to be limited to the sort of person who can understand the science, not "anyone with an LLM" - having an "intelligent", "reasoning" assistant who can help you through anything you don't understand does lower the bar quite a lot, and I would prefer there to be a fair amount of friction.

It's not like the material isn't out there - if you want to learn about this stuff, an LLM will happily point you towards Wikipedia and other public sources, it's just not going to walk you through the assembly.
