“If I would have asked people what they wanted, they would have said faster horses.”
Attributed to Henry Ford (the car maker dude); although Patrick Vlaskovits suggests Ford never actually said this.
If people had gotten faster horses rather than cars then the world would be a different place. For example, Ford introduced mass production techniques that where utilised in both the military (e.g. WW2) and commercial environments.
