Honestly it's very frustrating that Doomers/Decels rarely actually articulate how exactly the AIs will kill us all. The closest Darios gets is:

a) "it’s my worry that in 6–12 months such a swarm could be capable of taking over the entire internet with a persistent botnet"

b) "[the CCP] will be in a position to militarily dominate democracies (for example with AI-driven drones)"

Both land flat:

a) Botnets and online malware have existed for decades and there's no reason to think a "super-botnet" is achievable, let alone what they would gain from that (it would really be hurting them more than humans). Further, even the most advanced AI models have so far only managed to post normal cred stealers to public repos, well short of compromising a bank or military with refined security systems.

b) Even if the most sophisticated drone swarms from Ukraine were taken over by an evil AI, they would still not be able to overcome the physical limits of range and mass that would be required to overpower the US decentralized nuclear trident nonetheless that of any of the other nuclear powers.

Concerns of bioweapons similarly seem unlikely in the face of the laws of physics. The world is simply too decentralized and has enough existing adversarial relations for a new actor to wrestle total control. Yet while the negatives ring hollow, the positives are extremely easy to state - if AI researchers find productivity improvements in existing industrial processes to make them 10% more efficient, humans will directly feel and experience the raised standard of living. Even Dario clearly recognizes this in the intro to his article, admitting that humans already die of diseases only a few short years prior to being cured. I for one, would like the AI labs to focus on saving all of the people they can who are suffering and dying today, rather than trying to come up with reasons that they should be allowed to continue suffering and dying.
