AI risk debate: tszzl says classic risks won't extinction us, peer points to biorisk

A debate on existential AI risk: @tszzl argues none of the "respectable" AI risk factors in RSP/preparedness reports (nuclear, pandemics) come close to human extinction — only a grey-goo-like family of self-replicators could. @JMannhart pushes back that he's vastly underestimating biorisk: while accidental catastrophic bio via evolution-like dumb optimization is hard, at cosmic scale even a half-skilled optimization process operating in biology could pull it off. The exchange highlights the core split in AI risk assessment between lab-report frameworks and self-replicating-optimizer scenarios.
