A timeline tracing how the race to build ever-larger AI models collided with a growing movement to stop it — from the first safety warnings and open letters around 2022-2023, through the EU AI Act, US executive orders, state-level bills like California's, and the wave of nonprofit and labor lawsuits that culminated in demands to halt training on models deemed catastrophic. The spine of the story is the shift from voluntary pledges to binding litigation, and whether courts rather than legislatures became the real regulators of artificial intelligence.
