Big Tech companies are making a last-ditch effort to influence AI regulation in the US, with their lobbyists pushing for a comprehensive federal law that would preempt state-by-state regulations. This law would establish a single set of rules for AI across the country, overriding the current patchwork approach. The goal is to avoid a legally complex and potentially costly system where companies must comply with different regulations in each state. Senators Marsha Blackburn and Chuck Schumer have been involved in bipartisan efforts to pass legislation, including the Online Privacy Protection Act. The tech industry's pursuit of preemption is driven by a desire for clarity and consistency in AI regulation, as well as a desire to avoid stringent state-level rules1. This matters to practitioners because a federal AI law could have significant implications for the development and deployment of AI systems, and could either facilitate or hinder innovation in the field.
