The veto pen struck quietly in Sacramento, but its echo rippled through tech corridors from Silicon Valley to Washington, D.C. On September 29, 2024, California Governor Gavin Newsom rejected Senate Bill 1047, a measure that sought to impose safety protocols on advanced AI systems. This move arrives at a pivotal time, as nations worldwide grapple with how to govern technologies that could reshape economies and societies without unleashing unintended harms.
Background on SB 1047
Introduced by State Senator Scott Wiener in February 2024, SB 1047 represented one of the most comprehensive state-level attempts to address AI risks in the United States. The bill targeted developers of large-scale AI models—those trained with computational power exceeding 10^26 floating-point operations and costing over $100 million. It mandated safety testing, risk assessments, and emergency shutdown capabilities for these systems.
Proponents argued that such measures were essential to prevent scenarios like AI-driven cyberattacks or autonomous weapons proliferation. The legislation drew support from figures like Geoffrey Hinton, often called the “Godfather of AI,” who has warned about existential threats from unchecked AI advancement.
Key Provisions of the Bill
To understand the veto’s implications, consider the bill’s core elements:
- Safety Testing Requirements: Developers would need to conduct rigorous evaluations for potential harms, including misuse in creating biological weapons or disrupting critical infrastructure.
- Whistleblower Protections: Employees could report safety concerns without fear of retaliation.
- Annual Certifications: Companies must submit yearly statements confirming compliance, with penalties for violations reaching up to $150,000 per day.
- Attorney General Oversight: The state would gain authority to sue non-compliant firms, emphasizing accountability.
These provisions aimed to fill gaps left by federal inaction, positioning California as a leader in AI governance much like its role in data privacy with the California Consumer Privacy Act (CCPA).
Governor Newsom’s Rationale for the Veto
Newsom’s veto message highlighted concerns that the bill’s thresholds were arbitrary and could hinder smaller innovators while failing to address real-world risks from less powerful AI. He noted, “Focusing only on the most expensive models may give a false sense of security.” The governor emphasized a need for regulations that evolve with technology, rather than rigid rules that might drive companies out of state.
This perspective aligns with industry voices, including OpenAI and Meta, which lobbied against the bill. Critics like Fei-Fei Li, a Stanford professor and AI pioneer, argued it could stifle open-source development and California’s competitive edge in tech.

Reactions from Stakeholders
The veto sparked a mix of relief and disappointment. Tech executives praised it as a win for innovation, with Anthropic’s CEO Dario Amodei acknowledging the bill’s intent but welcoming the pause for refinement. On the other hand, safety advocates, including the Center for AI Safety, decried it as a missed opportunity, warning that delays could lead to preventable disasters.
Experts like Timnit Gebru, founder of the Distributed AI Research Institute, pointed out potential biases in the debate, noting how industry influence often overshadows public interest. In a narrative spotlight on Wiener, the bill’s author, he responded by vowing to reintroduce similar legislation, stating in a press release that “AI risks won’t wait for perfect policy.”
Expert Insights on Broader Implications
For those navigating AI policy, here are practical tips drawn from expert analyses:
- Monitor Federal Developments: With the veto, attention shifts to the Biden administration’s AI Executive Order from October 2023, which directs agencies to develop safety standards.
- Engage in Multi-Stakeholder Dialogues: Organizations like the AI Alliance promote collaborative governance to balance innovation and ethics.
- Adopt Voluntary Frameworks: Companies can implement internal audits based on NIST’s AI Risk Management Framework to stay ahead of regulations.
Globally, this decision contrasts with the EU’s AI Act, effective from August 2024, which categorizes AI by risk levels and imposes strict bans on certain uses. Analysts suggest the veto may encourage a patchwork of state laws, complicating compliance for multinational firms.
Looking Ahead: The Future of US AI Regulation
As AI integrates deeper into daily life—from predictive policing to personalized medicine—the veto underscores the delicate balance regulators must strike. Vividly, imagine boardrooms where developers now weigh voluntary safeguards against competitive pressures, or policymakers poring over data in dimly lit offices, crafting bills that could define the next decade.
In a reflective close, this event invites us to consider not just the technologies we build, but the societies they serve. With midterm elections looming and international summits like the upcoming UN AI Advisory Body meetings, the conversation on governance is far from over. Experts predict that without unified action, the US risks falling behind peers like China, which has implemented strict AI ethics guidelines since 2022.

Ultimately, Newsom’s veto serves as a grounded reminder: effective regulation requires nuance, collaboration, and adaptability in an era where AI’s potential is matched only by its uncertainties.
