I feel like you have drawn a line in the sand and said , "This is the proper amount of knowledge to have, anything more than it is wasteful and anything less is ignorant".

How did you verify your physics and engineering knowledge? Did you run hundreds of thousands of experiments to verify every single law and property of physics? At some point you are reaching a piece of data you learned from someone else and did not verify or that is an assumption because it's currently unknown how to explain or takes too much effort to verify while living your life.

On top of that, the OP was talking about how it was impossible to verify _everything_ in our lives nowadays. You mentioned nothing about biology or chemistry. How do you know your diet is the proper one? Are you sure about every chemical you interact with and how it affects you? Do you properly understand copyright and other IP law when you make a YouTube video using someone else's work? Did you get the right permits to put up that shed on your land that complies with the regulations from the 7 different layers of polity that cover you? Life is far too complicated to understand every facet and it only gets worse as we realize things are more complicated than we previously thought
