The idea
An algorithm needs no computer — any precise, finite, repeatable procedure qualifies, whatever carries it out.

A written recipe is an algorithm: exact amounts, ordered steps, and a finished dish standing as the output.
Where people slip
Machines made algorithms fast; the idea itself never needed one.
