The key quote is in the increasingly prescient 1979 IBM training manual: "A computer can never be held accountable, therefore a computer must never make a management decision."

That manual aged much more gracfully than the 1930s "Songs of the IBM," featuring lines like "The name of T.J. Watson means a courage none can stem / And we feel honored to be here to toast the I.B.M.," and of course classic American standards like "To G.H. Armstrong, Sales Manager, ITR and IS Divisions."
