Doctorow warns AI capital expenditure bubble faces catastrophic collapse
In his new book, *The Reverse Centaur’s Guide to Life After AI*, Cory Doctorow contends that global capital expenditure has reached unsustainable levels, predicting a market crash that mirrors the dot-com era but with far greater economic consequences.

Tech journalist and science fiction author Cory Doctorow has released a new book, *The Reverse Centaur’s Guide to Life After AI*, in which he argues that the artificial intelligence sector is in a speculative bubble driven by corporate growth narratives rather than material utility. Doctorow contends that the industry’s massive capital expenditure is unsustainable and predicts a catastrophic economic collapse when the bubble bursts, noting that global AI capital expenditure has risen from $700 billion to $1.4 trillion.
He distinguishes between 'centaurs', who use AI as a helpful tool to augment their work, and 'reverse centaurs', who are monitored, exploited, and held accountable for AI errors. Doctorow asserts that AI is currently losing money for every user and that the hype surrounding job replacement is a self-serving narrative used to justify investment. He predicts that while the bubble will be destructive, it may leave behind useful residues such as open-source models and cheaper hardware, similar to the aftermath of the dot-com bubble.
Doctorow argues that the current investment mania is fueled by firms seeking to maintain the perception of growth in saturated markets. He notes that while the web became more profitable with each user, AI is the "money-losingest thing our species has ever done," with every customer and every generation of technology losing more money than the last. He warns that seven AI companies currently account for more than a third of the stock market, passing around significant financial obligations that lack a material basis.
The author draws a sharp contrast between the social reception of previous technological bubbles and the current AI boom. While workers historically fought to adopt beneficial technologies, Doctorow observes that AI is often being imposed on employees, with some firms deploying surveillance tools to punish workers who refuse to use the technology. He suggests that the narrative of AI replacing workers is largely a fabrication designed to justify the enormous capital outlays required to sustain growth stock valuations.
Despite his criticism of the industry's financial practices, Doctorow maintains that he is not fundamentally anti-AI, citing useful applications such as local transcription tools and statistical analysis for human rights organisations. He believes that when the bubble bursts, the collapse of overvalued firms will leave behind a more robust technological foundation, including affordable hardware and creative talent freed from corporate constraints, much like the productive residue left by the dot-com crash.
