How is it irrelevant? Just because an effort existed before some change, doesn’t mean it can be repurposed and leveraged for other purposes. It’s the entire reason law and policy for government isn’t set in stone and is adaptable, because culture, technology and so on change.

The dynamic in this context absolutely has changed. Marginal cost to discover vulnerabilities from AI frontier labs and the big players has dropped significantly. The cost to patch is low, if you have access to certain resources. If you don’t, tough luck.

So this argument is essentially against the entire argument of AI alignment guardrails right now. Maybe you disagree with those, but I for one am happy they’re doing some things to protect against bio related warfare engineering. This is a case of cyber that’s about grey. Even there the labs have limited access to some and are choosing winners.
