Measuring a result of several variables, and claiming to measure only one without proper control tests. You know, science. The article's only measurements are of measure of 'economic output' and workers effort. These are of course a result of not just productivity provided by automation, but the distribution of this benefit across the peoples being measured. This is easily accounted for if one factors in the increase in elitist centralization of power and economic prowess that offsets the advances in productivity due to automation. A more complete scientific analysis would include such factors to tell a more complete picture.
