Why the 'We Must Act Now' AI Letter from 16 Nobel Laureates Faces Sharp Criticism — Especially Over China's Absence

The Letter's Core Arguments

The full statement, available at wemustactnow.ai, makes four concise points :

• AI may become radically more powerful over the next 10 years.
• This could drive an economic transformation larger than the Industrial Revolution, compressed into a much shorter timeframe — bringing both large-scale job displacement risks and opportunities for major gains in living standards.
• Economists, policymakers, and technology leaders must act now to understand the economics of transformative AI.
• The goal is to build the incentives, guardrails, and institutions needed to steer AI in a direction that complements humans and benefits society .

The letter deliberately does not call for a pause on AI training, nor does it prescribe specific policy instruments such as taxes, retraining programs, or safety bills . It is framed as a consensus statement from the economics establishment urging preparation rather than alarm.

Criticisms of the Letter

1. Geographic Skew of the Signatory List
A review of the signatories at wemustactnow.ai shows a stark geographic concentration. Roughly four-fifths of signers are from the US and Canada, and almost all of the remainder are from Europe . Notably, not a single signatory is based in China — a country that accounts for roughly half of all frontier AI model development and arguably has the world's fastest rate of AI adoption .

This absence has drawn pointed criticism. An opinion piece in the South China Morning Post (July 26, 2026), titled "The West is debating AI's future with half the world absent," argues that any meaningful debate on AI's global economic impact must include China, where the AI experiment is running at greater speed and scale and with different results . The piece notes that by excluding China, the letter's approach to a global economic transformation effectively excludes half the AI world .

2. Lack of Concrete Policy Proposals
Commentators have noted that the letter's 88-word length and four-sentence structure — while deliberately broad to attract a wide coalition — offer no specific policy instruments such as taxes, retraining programs, model audits, or safety legislation . The Cato Institute's podcast (July 30, 2026) raised the question of whether such a vague call to action can meaningfully influence policy .

3. Absence of Binding Regulation Despite Prior Warnings
Critics point out that multiple major AI warning letters since 2023 have asked governments to regulate AI, yet none has produced a binding law . This raises the question of whether "We Must Act Now" will suffer the same fate — generating headlines but no institutional change .

4. Ideological Breadth as a Mixed Signal
While the letter includes prominent economists across the political spectrum (from left-leaning Nobel winners like Paul Krugman and Joseph Stiglitz to libertarian-leaning figures like Tyler Cowen), some observers at the Cato Institute suggest this ideological diversity reflects the letter's vagueness rather than genuine consensus on solutions .

Summary

The letter's core argument — that AI-driven economic disruption could be larger and faster than any prior technological transformation, and that institutions are not ready — is widely seen as important and timely. However, the geographic exclusion of China is the most prominent criticism, undermining the letter's claim to speak for a truly global economic transformation. Combined with the lack of concrete policy proposals, the letter has been described as a well-intentioned but incomplete "all hands on deck" call that leaves the hardest questions unanswered .
