These systems
don't enable that. Building a bomb, spreading a bioweapon and hacking water/electrical misconfigurations are all trivially possible without AI. Courtesy to Unibomber, Aum Shinrikyo and the IRGC, respectively, for teaching society this.
In any case, how would AI regulation prevent any of these things? Shouldn't we instead focus on limiting access to bomb/bioweapon precursors and securing vulnerable endpoints, since that is the solution that saves lives regardless of how AI disseminates? Regulating AI is expressly dangerous, if it expands that societal blind spot. It'd be like regulating red mercury.
