The weapons of mass destruction trio (bio, chem, nuke) have long been a concern for world powers.

Nuke requires a long supply chain and massive resources, so the worry there is maintaining control of all of the existing nuke weapons. Except for Russia racing towards Turin no itself into a failed state by staying engaged in the war with Ukraine, I don't see the nuke equation has changed much in recent years. Perhaps N Korea is a worry, but they seem to just want attention and power. Iran pretends to have nukes and says they want to extinguish Israel and the US, but I interpret that as posturing to maintain domestic control and Israel seems excellent at countering Iran's threats.

Chemical weapons have traditionally been the easiest to create (like creating chlorine gas from mixing common household cleaners). The trick there has always been volume and how to disperse it. I suspect within countries, police will have to deal more with LLMs being abused that way.

Bioweapons will be easier than in the past. LLMs will lower the barrier to entry, but bioweapons are hard to create and much of what the superpowers learned thankfully isn't in the training set for LLMs. I doubt there is much that can be inferred by having agents learn biology from first principles.

Ultimately, governments are responsible for policing these threats. Sadly we are currently both cutting government systems which work different aspects of these problems and withdrawing from the multinational orgs (UN, WHO, etc) who do lots of the investigating and watchdog work that underpin lots of the US's intelligence related to these fields.

The US has a schizophrenic regulation policy of AI where we both want to sell Nvidia chips to China (David Sachs) and we don't want to sell the top chips to China (bipartisan policy prior to Trump). We also have a terrible AI regulation policy where David Sachs disables models on a call-to-CEO-on-a-Friday-evening basis after Andy Jasse calls him with a scary story which turns out to be missing lots of relevant info (eg. The exploits was discovered in Mythos, not Fable, and other open weights models were able to find the same exploits).

There's not much we can do at a government policy level while Trump is snoozing through the rest of his term. So we are dependent on the AI companies to police themselves, but it's clear from this report that it's insufficient to prevent all serious abuse of the models.
