There's no such thing as a dumb user. … There are only dumb products.

The line rejects the common habit in technology and design of blaming people for confusion, mistakes, or “misuse.” Instead, it shifts responsibility to the artifact: if many users fail, the product’s interface, affordances, instructions, or underlying assumptions are at fault. The quote encapsulates a user-centered design ethic—treating errors as diagnostic signals and designing systems that anticipate real-world constraints, varied skill levels, and imperfect attention. It also functions as a moral stance: calling users “dumb” is a way to excuse poor design and avoid accountability. In practice, it argues for empathy, testing, and iterative refinement rather than contempt.
