Maybe that was true a long time ago. You had to trust someone with the skill, and if you did not have the skill yourself, you had absolutely no way to understand your own dream project. Will it work? I am taking investment, how can I not know what is going on? When will we launch? What breaks when we scale? How is our system holding up? We just hired developers and we have no idea, none in the world, what they are actually doing.

Would you run across a six lane highway blindfolded, with a pinhole to see out of? Same thing. That is what building without understanding feels like, and founders do it every day because they think it is the only way.
