For some intuition on the difficulty in synthesis, note that explosive chemistry and synthesis is comparatively trivial, yet there are relatively few terror attacks that go beyond commercial-off-the-shelf compounds and almost none that do it well.

Personally, I think this model would be a boon for public safety because contract synthesis operations could use it to screen incoming requests for "nerve gas but changed up a bit." Basic chemical intuition probably already gets them far in this regard, but a published model could be standardized and mandated.

Someone else in the thread asked about next steps. Those would be good next steps.
