Agreed. I think we might be talking semantics here. It just depends what you consider to be asking the users. The Henry Ford quote is just meant to say that you can't take advice from users literally because they'll only tell you what they're already used to. To me, asking the users is not a literal asking, but rather, a questioning the shortcomings and potentials of the current environment.

In the UX community, it's well known that you don't ask people what they want, which is why they have all those clever UX research methods.
