“but to the degree that large industry develops, the creation of real wealth comes to depend less on labour time and on the amount of labour employed than on the power of the agencies set in motion during labour time, whose ‘powerful effectiveness’ is itself in turn out of all proportion to the direct labour time spent on their production, but depends rather on the general state of science and on the progress of technology…labour no longer appears so much to be included within the production process; rather, the  human being comes to relate more as watchman and regulator to the production process itself…as soon as labour in the direct form has ceased to be the great well spring of wealth labour time ceases and must cease to be its measure…”
