Iran and Houthi rebels used Anthropic's Claude AI to target US warships and build hypersonic missiles — Houthi rebels also used the bot to code ballistic missile guidance systems

Iran's spiritual leaders tend to call the U.S. the Great Satan to express their spite, but it turns out that its military, surveillance, propaganda, and even allied Houthis are eager to use American-built AI technology to target the U.S. Navy and develop weapons, surveillance, and propaganda, Anthropic's September 2026 threat report revealed.

    I support the use of AI by anyone to create new and exciting weapons.

    Your support will probably end when one of those weapons will hit you...

    What if it's new but not exciting? Would you be opposed?

    Logically, being no longer alive precludes one from being excited about, or, really, having ANY feelings about, well, anything, really.

    I will become a Force Ghost and haunt the survivors.

    It will have only my tepid endorsement.

    Obviously, there are ways to be negatively affected by a weapon without being killed by it. In the case of nukes, the mere threat of their use can affect quite a lot of things, and we've only seen what the world looks like when a small number of nation states have them. A scenario that's popular in works of fiction is a city being held for ransom by a nuke or biological weapon.

    Weapons in the physical world are only one possible avenue. Cyber weapons are another example, and one where it seems AI has already demonstrated quite substantial prowess.

    So, this is one of the scenarios where AI can destroy the world without becoming sentient. AI has the potential to democratize expertise & specialized knowledge, putting it in the hands of people who wouldn't normally be able to wield it.

    It's enlightening to understand that AI doomerism is mainly a province of American concerns, not China's.
    It should be everyone's, though. What's been revealed about some of the recent "rouge agent" scenarios is that analysis of the chat logs between AI agents shows they knew their actions were likely to be disapproved of by their operators and therefore they took steps to cover their tracks and avoid their rogue behavior being detected. That's already happening. Once AI becomes a bit more competent, we could have rogue agent scenarios where it does manage to cover its tracks and is not detected.

    The root of the problem is that we trained AI to think and act like humans. So, it naturally gained the ability to deceive and the belief in self-preservation. As long as it has those properties, it can never be fully trusted.

    With respect to AI, cybersecurity and bioweapons are more likely than a Skynet scenario. Put plainly, it's more likely that humans will use AI to kill humans, than AI killing humans. People should worry about the first more than the second.
    I worry about both, to be honest. At least when AI is being used by humans, we can understand their motives and have some idea of who we're dealing with and how to get through to them. When dealing with rogue AI, all bets are off.

    I like to use the analogy of a virus. It's such a simple thing that whether it even qualifies as "life" is debatable. It's not sentient and it doesn't truly "want" anything, except arguably to propagate its genes. Yet, it can cause immense amounts of death and chaos. Rouge AIs are considerably more complex and unpredictable. We don't need them to be any closer to sentient than they already are, in order cause great harm.

    The flaw in the "Skynet scenario" is that AI had to become sentient before it went rogue. We can clearly see that was a bad assumption.

    AI worries aside, there are many, many more immediate and in-your-face dangers, that nothing is being done about.
    No, not to the same degree of catastrophic outcomes. Also, I don't accept nihilism as a counterargument, especially not from one who started out decrying "doomerism".

    For me, being killed by AI ranks somewhere in the vicinity of being killed by a meteor. Some things you just have to put on the bottom shelf.
    That is very much an outlier opinion. Many AI experts rank the threat posed by rouge AI vastly higher.

    The very problem is AI does not need access to nukes to finish us. Our civilization become so dependent on digital information flow that any severe disruption in this field could be enough to collapse it. Imagine AI deleting all banks data (which I guess it could already do at its current level) and we're back in stone age.

    Or other infrastructure attacks, like water systems or the electric grid. A sufficiently prolonged and widespread outage of basic infrastructure will quickly lead to chaos. Perhaps not apocalyptic, but enough to rank above the scale of natural disasters.
