i don't know what exactly i mean by the title;
at best, i can only explain it by example.
a month ago I was absolutely delighted to convert one of my old proofs .. which initially relied on weak star cοmpactness .. into a purely geometric argument.
at the time i thought this was the coolest thing ever .. and i still think it was worth the effort .. but it's been a month and now i have to stop myself from saying ..
wait: shouldn't it be obvious..?
as another example: whenever i wrote an exam for one of my courses, i'd take it myself and multiply the elapsed time by 4; if the product was less than the length of the exam period, then the exam was too hard for the course.
now i'm considering changing it to a factor of 5.
either students today are slower or i'm getting faster .. and i'm almost sure that i'm not getting any faster.
