"What Clayton Christensen Got Wrong" is an essay by Ben Thompson, published on Stratechery on September 22, 2013. It separates two theories of disruption commonly attributed to Clayton Christensen and argues that one of them — low-end disruption — does not apply to consumer markets, where user experience cannot be overshot.

Two theories of disruption
Thompson separates two distinct theories he says are often conflated:
- New market disruption (from 1995's Disruptive Technologies / The Innovator's Dilemma) — incumbent companies ignore new technologies that do not serve their best customers; the new technology matures along different attributes and eventually takes the market. Thompson accepts this theory.
- Low-end disruption (from Christensen's later work, The Innovator's Solution) — modular providers eventually become "good enough", integrated incumbents are overshot, and low-priced modular providers take the market. Thompson rejects this theory for consumer markets.
Rejection of low-end disruption in consumer markets
Thompson argues that low-end disruption rests on three assumptions, all of which he says fail in consumer markets:
- Buyers are rational. He treats this as true for B2B, where CIOs justify purchases on documented features, but false for consumers, who weigh user experience, brand, design, and gratification.
- Every attribute that matters can be measured. He says this fails for ease-of-use, look-and-feel, design, and "the experience of a product." In his account, user experience is impossible to overshoot — no one ever defected to an inferior product because the better one was too pleasant.
- Modular providers can become "good enough" on every attribute. He says this fails for hard-to-quantify attributes, because modularization incurs costs in design and experience that vertical integration can avoid.
Thompson characterizes Christensen's research base — disk drives, PCs, mortgage banking, microprocessors, and software — as B2B-tilted, and argues that Christensen's own predictions of Apple's disruption consistently fail because Apple operates in a consumer market with different rules.
Empirical anchor
Thompson cites Benedict Evans's 2013 essay "Apple, Open and Learning From History" for the claim that the 1990s PC market was roughly 75% corporate, which he says is why low-end disruption fits PC history. He notes that the smartphone market has the opposite ratio.
Alternative framework
In place of low-end disruption for consumer markets, Thompson proposes Michael Porter's three generic strategies — cost leadership, differentiation, and focus — with differentiation specifically encompassing design and experience. He cites Apple, BMW, and premium textiles as firms that compete on differentiation sustainably, in ways he argues low-end-disruption theory cannot explain.
Relevance to AI competition
The Christensen/Thompson distinction informs the analysis of whether open-weight models constitute low-end disruption of frontier labs. A Christensen-school reading would predict frontier labs lose to "good enough" open weights such as DeepSeek, Llama, and gpt-oss. A Thompson-school reading would predict that the consumer-AI market continues to favor user-experience leaders — ChatGPT and the Claude apps — regardless of API-cost convergence, while the enterprise and API market may follow Christensen's pattern given the rational-buyer dynamic. See Open-Source AI / Open-Weight Models and AI Promise and Chip Precariousness. On the same logic, Thompson's framework implies that AI assistants will not commoditize in consumer markets, where it treats user experience as a moat, and it frames the "Nokia / Blackberry comeback" thesis — frontier labs being displaced by open weights — as a category error.
