You know, some things are universal truths that never change and repeating them over and over seems unneeded. Except the "ground below them" flows. Old engineers retire, young students enter the field. You might have heard them tens of times. I heard most of them second or third time. Few of them first time. Probably there are people on this forum heard most of them for the first time. And there's always a chance someone will say something you don't know yet too. If you find them boring, don't read - apparently they aren't addressed to you. I found it interesting, but probably re-reading the same article in some 20 years I will be as bored as you are.
