This is a weird way to think of it, making it seem as thought its just a matter of chance whether the founder is right or not. The difference, if there is one, is that some founders can pivot when they see their approach won't work or, at least, throw in the towel before people die or too much many is wasted.

Maybe that makes them bad startup founders? I don't know. In my opinion "Startup Founder" is a role which should play second to "ethical human being."
