I truly don't see any major problem with what they're doing. For any current significant risk (security, bio risks), their models are notoriously useless.
It's kind of like saying you can't kill everyone with weapons when you're looking at what you can buy at the local Walmart and not what's in the 1000 foot deep missile silo.
Also, it's kind of a once you build it, it's too late kind of issue. No model will be good enough, the problem is still in the future, we're all dead.
