This is because to build a pipe bomb you need difficult to source materials. This is not the case for other types of threats (cyber / bio).

I personally have no need for an LLM which will readily explain how to cut up the genotype of smallpox into small chunks which can pass the screening at the bio-labs, and can be readily assembled into the real thing by a second year lab-student.

Anyone who knows how to operate a biolab properly will already know how to do such things. This is not really an in your basement thing. Dangerous chemistry is much more of a risk.

Ignorant question but won’t there be much smarter teams if people using LLMs to workout how to mitigate these threats. It seems like more of a problem if only a few people have access.
