Ask HN: How is AI actively a threat to humanity if it's only online?
A user questions the validity of AI existential risk arguments, noting that current AI capabilities are largely confined to the digital realm. The author argues that physical infrastructure, such as factories and weapons systems, lacks the necessary internet connectivity or programmability for AI to directly control them. Consequently, the user suggests that apocalyptic scenarios rely heavily on human manipulation or the future development of easily hackable autonomous robots.
- ▪The author argues that AI cannot directly control physical manufacturing because production lines use single-purpose machines that are not programmatically alterable.
- ▪Weapons systems and bio-engineering facilities are not accessible via the internet, meaning there are no API endpoints for AI to launch attacks or release pathogens.
- ▪The user believes that significant AI threats to humanity require either the manipulation of human behavior or the creation of internet-connected intelligent robots.
- ▪Current AI risks are acknowledged to include hacking, spreading misinformation, and generating insecure code, but these are viewed as distinct from existential destruction.

Opening excerpt (first ~120 words) tap to expand
That's always been something that's left me confused here. Yes, an AI can be dangerous by hacking websites and company systems or flooding social media with scams or fake news. Yes, AI generated code can have security issues that a developer doesn't catch because they didn't review it properly.But isn't there a pretty big jump from that to "can destroy humanity"? Like say, a jump involving a society not run by the internet?Because if an AI takes over the systems at a factory, it can't really do much beyond what the factory could already do.
