The Software & Information Industry Association (SIIA) joins 11 organizations to express our opposition to AB 3204 (Bauer-Kahan). This bill’s mandated disclosures are not only impractical if not infeasible, but they can also be rather invasive. To the extent that the intent is to promote transparency and understand the degree to which consumers’ personal information (PI) is being used to train AI systems, we believe that the approach taken by AB 3204 is akin to taking a sledgehammer to crack a nut. We are unclear what the end goal of creating a central repository of these businesses is, when reasonable disclosures could accomplish the same purpose without incurring incredible costs to the state and to businesses.
