I am not sure what you mean here. There exist plenty high-concern biological threats that dont need any AI help. Human oncovirus design is low on my concern list (immunity is diverse), and in any case it does not need AI—rather labspace. Disgruntled high schoolers or undergrad chemists can do way more damage from readily available materials without AI and without research delay. As can nature (or amateur biologists without AI) by mixing bats with their animal of choice and waiting a while. If/when any scary global events like covid happen again, I sure hope we have true superintelligence to help us navigate it quickly.
