AI Slowdown Warning Exposes $3 Trillion Market Wager, Goldman Sachs Warns of 20% Downside

Anthropic CEO Dario Amodei's call for deliberate restraint in AI development has exposed the market's vulnerability to diminished innovation—with stock valuations built on an assumption of uninterrupted progress. Amodei published an essay titled "We Must Pace the Frontier" on September 12, arguing that AI systems are approaching capabilities that demand immediate safeguards, including swarms of autonomous agents and coordinated cyberattacks that could materialize within six months. OpenAI's Sam Altman and Elon Musk quickly endorsed the position, triggering a global technology selloff within hours.
