Sorry, WADR, I have to "niggle" here a bit...
You can compare the mechanized version with the hand version.
In some respects you have to, to really understand the shortcomings of the mechanized processes. Simply because when you put aside the social and cultural impact of replacing skilled workers with machines, the machines are just another kind of tool.
If the objective results of a machine process are as good or better than the results of doing it with simpler tools then, "no harm, no foul."
But you have to be objective...seriously, determinedly, objective.
