  "textContent": "Wishful thinking\n\nA.B. 2047 would require 3D printers sold in California to use government-approved algorithms that scan print jobs for supposed “firearm blueprint files” and block flagged prints. But the technology this bill mandates cannot reliably do what it is supposed to do.\nOrdinary objects like props, repair parts, tools, and toys can share geometric similarities with firearm components, meaning any detection system will produce false positives. Meanwhile, someone intent on making firearm components can find ways to bypass algorithms entirely, create undetectable designs, or simply build a 3D printer with common components.\nAlgorithms can’t detect intent. This bill signs up California for an expensive game of cat and mouse that only inconveniences people following the law.\n\nAttack on Open Source\n\nThis bill goes further than any other like it introducing criminal penalties for the disabling or circumvention of these systems. In practice, this threatens open-source firmware, third-party software tools, repair modifications, and independent innovation around 3D printing technology.\n\nSurveillance Lock-in\n\nA.B. 2047 paves the way for manufacturers to lock users into proprietary ecosystems, restrict repairs, and drive up costs. The requirements can also only be feasibly met with cloud-connected AI scans of every print, a surveillance apparatus prone to misuse and stifling lawful speech.\n\nWe’ve also learned from the history of Digital Rights Management (DRM) that giving companies the ability to write untouchable code, shielded by criminal penalties, leaves the consumer worse off. It robs us all of the ability to choose the right tools and improve what we already own—while creating a hotbed for vulnerabilities security experts aren’t allowed to fix.\n\nOnly the Beginning\nOnce this infrastructure exists, it won’t stay limited to firearm-related files. Systems designed to monitor and block prints can easily expand into copyright enforcement, political censorship, or broader restrictions on lawful expression and innovation.\nCalifornia must reject print censorship, and we’re running out of time. Contact your Assemblymember today and tell them to vote no on A.B. 2047.",
