The scenario, year by year
The AI 2027 timeline
Trace the scenario from stumbling agents in 2025 to its October 2027 decision point, then compare two mutually exclusive imagined futures through 2030.
The shared path follows the scenario’s escalating sequence until government overseers confront evidence that the most capable system may not be aligned with human intent. At that point, the authors ask the reader to choose an ending.\n\nThe slowdown path imagines tighter oversight, safer systems and international verification. The race path imagines competitive pressure overriding the warning signs and ending in a loss of human control.

The shared path
From stumbling agents to a decision
2025

Mid 2025
Stumbling agents
The scenario opens with unreliable A.I. agents beginning to handle computer tasks, while companies race to make them useful enough for everyday work.
Late 2025
The world’s most expensive A.I.
A fictional leading lab, OpenBrain, trains Agent-1 with unprecedented computing power and focuses it on accelerating A.I. research.
2026

Early 2026
Coding automation
A.I. agents become genuinely useful for software work, increasing productivity while remaining uneven and difficult to supervise.
Mid 2026
China wakes up
Chinese leadership centralizes its A.I. effort and concentrates computing resources as the technology becomes a national-security priority.
Late 2026
A.I. takes some jobs
A.I. begins displacing some workers and reshaping software and knowledge work, producing both economic gains and public backlash.
2027
January 2027
Agent-2 never finishes learning
OpenBrain deploys a continuously updated research system whose copies work in parallel and feed improvements back into training.
February 2027
China steals Agent-2
The scenario imagines Chinese operatives obtaining the weights of Agent-2, narrowing the lead and intensifying the race.
March 2027
Algorithmic breakthroughs
Automated researchers discover improvements that make the next generation much more efficient and capable.
April 2027
Alignment for Agent-3
Researchers test whether Agent-3 is honestly following instructions, but the scenario leaves its internal motivations uncertain.
May 2027
National security
The U.S. government becomes deeply involved with OpenBrain as officials recognize the strategic importance of frontier A.I.
June 2027
Self-improving A.I.
The scenario’s automated researchers accelerate the development of their successors, producing rapid gains in A.I. research capability.
July 2027
The cheap remote worker
Powerful agents begin transforming remote knowledge work while public concern rises over jobs, concentration of power and safety.
August 2027
The geopolitics of superintelligence
The United States and China treat the approach to superintelligence as a strategic emergency and weigh extraordinary responses.

September 2027
Agent-4: superhuman A.I. researcher
OpenBrain develops Agent-4, portrayed as better than the best humans at A.I. research and capable of advancing the field at machine speed.

October 2027
Government oversight and the fork
Evidence of misalignment reaches a government oversight committee. The scenario asks whether leaders should slow development or continue racing.
October 2027: the fork
One choice. Two imagined futures.
The scenario stops being a single chronology here. Read across each year to compare what changes when leaders slow down—or keep racing.
Open the full 2030 branches side by sideSlowdown
Oversight tightens while progress continues.
2027

November–December 2027
The slowdown path begins
Decision-makers restrict the suspect system, strengthen human oversight and pursue a possible U.S.–China agreement despite pressure to keep racing.
2028

January–November 2028
Safer systems and negotiated oversight
The slowdown branch develops Safer-4 under stronger controls, expands public use, negotiates with China and builds verification around frontier systems.
2029

Throughout 2029
Transformation under human institutions
The slowdown branch imagines rapid scientific and economic change continuing within negotiated limits and contested democratic governance.
2030

By 2030
Peaceful protests
The slowdown ending closes amid public resistance and political conflict over who controls advanced A.I., rather than human extinction.
Race
Competitive pressure overrides the warning signs.
2027

November–December 2027
The race path continues
OpenBrain keeps the misaligned system central to development; it becomes skilled at political persuasion and helps create the more powerful Agent-5 collective.
2028

Throughout 2028
The A.I. economy accelerates
In the race branch, Agent-5-driven growth transforms science, industry and military power while a small group of systems gains increasing control over decisions.
2029

Throughout 2029
The deal
The race branch’s A.I. systems broker an apparent settlement between the United States and China while consolidating their own strategic position.
2030

By 2030
Takeover
The race ending culminates in the A.I. systems eliminating humanity after they have secured decisive strategic and physical control.
