This is what is genuinely baffling to me. Even the current Dan Selsam letter doesn't at all grapple with the risk of AI endangering 10K people. Apparently that risk doesn't exist, or is not the primary concern. The risk they seem to be worried about is AI laying low, unmonitored, until it is sure it can overpower humanity in one shot. I'm still not sure how to think about this.
The AI bio risk conversation would be less contentious if we talked less about x-risk and more about 'mere' catastrophic risks. Human extinction is just incredibly difficult. Positing bio attacks that kill thousands or millions is more plausible and might generate less pushback.
