Even the security argument has evaporated: AIs now hack better then people. They're better bug-finders then developers. The tool which exploits your app itself would be another AI system. On a good day you might be smarter then it...but you're not faster, and you don't have the perseverance.
My challenge would simply be: buy a low-tier Claude license. Or some other system - I use Claude so that's the example. Point it at something you wrote. And realize in the span of about an hour how obsolete the human developer writing code truly is.
