I am of course quoting from a famous essay by Leonard Read, the economist in the 1950s, called "I, Pencil" in which he wrote about how a pencil came to be made, and how nobody knows even how to make a pencil, because the people who assemble it don't know how to mine graphite, and they don't know how to fell trees and that kind of thing.
Oczywiście cytuję słynny esej Leonarda Reada, ekonomisty z lat 50tych pod tytułem "Ja, Ołówek" w którym opisał jak zrobiono ołówek i że nikt nie wie jak go zrobić, bo ludzie w fabryce nie wiedzą jak wydobyć grafit. Nie wiedzą jak ścinać drzewa itp.
