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

Additional Information: This quote is from product designer Timothy Prestero's 2012 TED Talk about the importance of designing products for real-world use. Specifically, Prestero discusses a project in which he helped design a newborn incubator and the challenges this project involved. The quote has a similar meaning to the saying "The customer is always right." It means that if the customer (or user) has a problem with a product, it is not the fault of the customer, but of the product's designers.
