The quote is alleged to be Henry Ford, and I've always encountered it as "better horse."

In either case, the customers aren't stupid but instead are using the language and paradigm they are familiar with to describe their needs. Ford did indeed provide a faster/better horse, because the horse was the main means of non-human motive force in the US.

The technologist's job is to understand the universal of possible solutions and to understand the customer's needs and goals, which often includes interrogating and parsing the customer's language/worldview, and craft a product that achieves those needs/goals (and doesn't introduce negatives that overwhelm the benefits).
