Sanders Bill Proposes Permanent Ban on Superintelligence, Up to 20 Years in Prison

On September 24, Senator Bernie Sanders and Rep. Greg Casar introduced the Ban Artificial Superintelligence Act, proposing a permanent ban on superintelligence, a pause on frontier AI development, up to 20 years imprisonment for violators, and asset forfeiture for companies. The bill remains a proposal with uncertain legislative prospects, but its radical provisions triggered polarized reactions across the AI community, making it one of the most aggressive congressional attempts to restrict frontier AI.

Confirmed

• Per Krueger's endorsement thread and rohanpaulai's summary, the bill's core provisions include: creating a federal Department of AI; permanently banning "superintelligence" (systems exceeding human cognition in most domains or capable of severe harm); banning "superintelligence precursors" including automated AI research and recursive self-improvement; pausing training and deployment of "advanced AI" models at or above 10^25 FLOP/operations until the department establishes governance; asset forfeiture and up to 20 years imprisonment; and pushing international coordination.
• Cambridge AI safety researcher David Krueger publicly endorsed the bill, declaring an "AI emergency"; MIRI also endorsed it, as did employees at several leading AI companies. PauseAI launched a phone-calling campaign urging constituents to press their representatives.
• NBC News covered the proposal. Polymarket prices the odds of a US AI safety bill passing before 2027 at only 13%, with about $165K in volume.

Unconfirmed

• An analysis by @1a3orn of the draft PDF suggests the ban covers not only superintelligence but any system displaying "superintelligence precursor characteristics," potentially capturing many current models—this reading awaits legislative testing.

Why it matters

• If the precursor-characteristics clause were enacted, it could directly restrict mainstream model development and deployment; the ban on recursive self-improvement targets a current mainstream research direction.
• Reactions split sharply: Krueger and MIRI urged emergency action; DavidLinthicum called it bipartisan "fear-driven legislation"; VraserX argued a permanent ban is a terrible way to share AI-created wealth, questioning why protecting workers means preserving the necessity of work; David Sacks' camp criticized overregulation; prediction markets price low passage odds.
• Margaret Mitchell pressed Krueger on the distinction between "AI escaping our control" and "we developing AI in an out-of-control way," arguing this subtle divergence is fracturing the safety community's legislative narrative.
