Agreed (albeit I also agree with Ken2′s comment in response). One other point, though, is that there are some limitations one can know based on our current ability to do experiments. Perhaps one of the string theories is right about physics at Plank energies—but we currently have no access to particles at those energies, which severely limits how well we can currently test such theories. Given two theories which make different predictions in this regime, but which have nearly indistinguishable low energy limits, we have essentially no current way to tell which is more likely to be true.

I agree with the original premise that there are too many people for one person to know everything or even everything that is known.
Something I read some years ago is that everyone knows something that you do not. In that regard, everyone is your master.
