But even then, the debate isn't about whether open weight bioweapons exist today: it's about whether they will exist in the future. I think Amodei's argument here makes a lot of sense: "what I believe currently keeps us safe in biology is not 'defenders', or even the availability of materials, but a negative correlation between intellectual capability and desire to commit catastrophic harm. Previous technologies like internet search or even DNA synthesis were nowhere near powerful enough to break this correlation, but I worry that at its current rate of progress, AI will do so very soon."
(I'm not just spouting off; I put my time where my mouth is. I used to work in big tech, but I left for a much less well-paying job building an early-warning system for engineered pandemics.)
