When Dean Ball, O<br>Fragile EquilibriumEconomics, innovation and challenging the status quo.<br>By Brandon Carl
When Dean Ball, OpenAI’s chief of strategic futures, recently reflected on Kimi’s new K3 model, he did more than critique a competitor. He inadvertently lit a fuse on Silicon Valley’s loudest sectarian dispute. The post seemingly positioned open-weight models—which release their inner mathematical blueprints to the public—as “inherently decelerationist.”<br>“Open-weight models are inherently decelerationist, and I’m continually surprised to see the so-called ‘accelerationists’ so excited about open-weight models. I suspect the reason they are is that they know open-weight models are effectively ungovernable, and they simply like the overall cloak of ungovernability open-weight models create over the whole of AI. It’s not a bad strategy; it reminds me of James Scott’s recounting of the hill people in ‘the art of not being governed.’ Still, in the end, open-weight models deter further AI capex.”
The term “decelerationist” exists only in opposition to accelerationism—the view that rapid technological proliferation hastens innovation and social benefit. Decelerationism, by contrast, denotes anything that slows capital formation and therefore delays those gains. Why might open weights qualify?<br>Thanks for reading Fragile Equilibrium!

There is much to unpack here. If the claim is that open weights deter capital expenditure and therefore slow the pace of frontier development, the argument must rest on economics rather than aesthetics. That requires examining, in order: whether tokens become commodities; China’s capacity and appetite to build AI infrastructure; where value accrues along the value chain; whether today’s training paradigm is even durable; and, ultimately, who captures the financial upside.<br>Capital intensity and the Chinese question
At the moment, training large language models is expensive: specialized chips, vast data centers, scarce engineering talent and oceans of data. Investors underwriting such projects expect durable cashflows. If open weights compress future revenues by making models easier to replicate or fine-tune, the net present value falls. Capital, in theory, retreats.<br>That logic takes on geopolitical color when China enters the frame. While it is easy to caricature the country through a nationalist lens, the country’s economic transformation is not in doubt. Through successive “Seven Year Plans”, China has built a manufacturing base of extraordinary scale, lifting hundreds of millions into the middle class. Where it directs capital—steel, solar, electric vehicles—it has often reshaped global markets.<br>Post internal industrialization, the question has been what happens as it points its powerhouse externally. Solar panels and batteries were early answers. Artificial intelligence infrastructure may be another. If “factories” once produced steel, tomorrow’s produce tokens. With a low cost of capital and tolerance for overbuild, China can subsidize capacity, compress margins and unsettle foreign incumbents. Concerns about dumping in steel and solar illustrate the playbook.<br>From this vantage point, open weights appear to amplify the threat. If intelligence can be replicated cheaply and deployed widely, the ability of American firms to monetize frontier models weakens. A world awash in subsidized, open-weight intelligence might indeed deter private capital in higher-cost jurisdictions.<br>Were one to stop here, the decelerationist case would seem plausible. But it is anchored in a snapshot of today’s training paradigm and today’s revenue expectations.<br>Training paradigms and the locus of value
Current models are largely trained de novo: vast corpora ingested, weights frozen, then fine-tuned and reinforced. Each generation is, in effect, educated from birth. Continuous and online learning point to a different future—machines that accumulate knowledge, discard errors and adapt incrementally, more like humans than static snapshots. Such approaches could materially reduce upfront capital expenditure.<br>François Chollet, a long-term fixture within AI, has argued that:<br>AI in 2040 will not be built on the stack we are using today. It will be much closer to optimal. The current stack has 3–4 orders of magnitude of data inefficiency and 4–5 orders of magnitude of compute inefficiency. Near-optimal AI is what symbolic learning will deliver. People struggle to differentiate fluid intelligence from knowledge because, given enough preparation, memorized templates become a solid substitute for on-the-fly adaptation.
If correct, today’s capex-heavy regime is transitory. Even more fundamental is the question of where value...
