state machine
A state machine is a mechanical concierge of logic, unemotionally binding inputs to outputs like a tireless servant. By faithfully mapping what happens next into tables, it offers a world where free will and improvisation are strictly forbidden. Before the multiplying number of states, even the most elegant design quickly devolves into incomprehensible black magic. Developers can only pray for the unknown bugs that arise in the gaps, making debugging a kind of religious ritual. Those who dream of technological progress are compelled to grind their teeth before this invisible labyrinth first.
