What is a magic word? A word which is not just a symbol? A causal word?
Such spells exist. Just say “noise” to yourself, and it appears. Shout “police!” long enough and you will summon the demon you name. “Confusion!”, in company. “Speech-act”. “Disquotation” après-moi. “Entropy!” arguably.
(All quite aside from code, the living words eating the economy and the intellect, and so the world.)
