Good point, but taken to the extreme, if you listen to people too much they'll tell you they want a faster horse. You have to combine the aspirational thinking

Good point, but taken to the extreme, if you listen to people too much they'll tell you they want a faster horse. You have to combine the aspirational thinking of "let's build a self-driving car" with the day-to-day grind of actually building it. Without the first, you end up in the local maximum you describe, without the latter you land in the "talk is cheap" box. My post is about the fact that you can in fact leave your job and go through a phase of prototyping one product after another, and deliberately testing each idea for not just how great it sounds but how buildable it is.
