If you perform a complex function (e.g.
software) using
people rather than machinery (hardware), the
people who carry out the function are fleshware.
Nobel prizewinner Richard Feynman's describes designing a fleshware 'super-
computer' made of
punch card machines and human calculators to do the complex calculations needed to design the atom
bomb at Los Alamos.
There are many other instances in
pre-computing era organizations where complex calculations were carried out by rows of nerds with pencils and papers. Earlier implementations include vast libraries of medieval monks acting as printing presses by writing out manuscripts and pairs of sailors (often duplicated for accuracy) acting as speedometers and sonar by casting knotted lines behind the
ship, timed against one or more sand hourglasses and leaded lines below it for depth.
