Casar and Sanders Propose Ban on Artificial Superintelligence

Representative Greg Casar (D-Texas) and Senator Bernie Sanders have introduced the "Ban Artificial Superintelligence Act," legislation designed to prohibit the development of AI that exceeds human control or possesses the capability to develop weapons of mass destruction. The move signals a push to treat advanced AI as a baseline national security and existential threat rather than a commercial concern.

Casar is urging the United States to spearhead a new era of "AI diplomacy," proposing that the establishment of international safety agreements be a top priority for the upcoming United Nations meeting. He argues that the U.S. should pursue global treaties modeled after Cold War nuclear nonproliferation agreements to prevent a catastrophic escalation in capabilities.

A Shift Toward Global Treaties

This legislative push arrives as industry leaders from OpenAI, Google, and Anthropic have called for a coordinated slowdown in frontier research. However, Casar has dismissed these voluntary industry pauses as insufficient "pinky promises," arguing that corporate self-regulation cannot replace federal mandates. He further criticized Republican leadership, specifically Speaker Mike Johnson and Donald Trump, alleging that they have prioritized campaign contributions from the AI industry over the implementation of necessary safety guardrails.

To provide leverage in international negotiations, Casar advocates for strict domestic guardrails and export controls. He contends that such measures can slow the development of dangerous AI globally, noting that Chinese AI models currently train on American models. By restricting the flow of these foundational technologies, Casar believes the U.S. can pressure other nations into signing binding safety agreements.

The Stakes of the AI Arms Race

Framing the technology as a potential "superweapon," Casar argues that the current competitive trajectory is unsustainable. "No one can win the AI arms race," Casar stated, adding that the primary goal must be to end the race entirely to protect global populations. He maintains that while the U.S. should remain a technological leader, it must simultaneously lead the world in diplomatic efforts to constrain the technology.

Public sentiment appears to align with this cautious approach. According to polling from Data for Progress cited by Casar, 68% of voters support the Sanders/Casar bill to pause AI development and ban superintelligence.

The Path Forward

While the bill establishes a clear legislative intent, its path to passage remains uncertain given the current political divide over AI regulation. Observers will be watching the upcoming United Nations meeting to see if Casar's call for a treaty-based international regime gains traction with global allies. The effectiveness of using export controls as a diplomatic tool to force international compliance also remains a point of debate among policymakers.
