It seems like you're talking about chemical weapons.

Which is fair, they are very easy to make without the assistance of an LLM, and I don't hear about that kind of thing in the news.

I was talking about biological weapons like gain of function and that kind of thing.

The implied question was 'Should companies like Meta publish open weight models when they could theoretically be subverted by malicious users?'. So far as I'm aware there are few people worrying about this kind of thing. Bill Gates for one. But apparently it's off topic and/or not interesting, or not welcomed as a discussion point.
