Sorry, my wording was imprecise; when I said "educator", I meant popular science educator, along the lines of Asimov, Sagan, Neil DeGrasse Tyson, etc. I can't think of anything Schwinger ever wrote or a public lecture that he gave that would be accessible to a general or even a semi-technical, non-physicist audience.

But, beyond that, yes, I think we're largely in agreement.
