This makes the process of \”throwing off\” (finishing) the frame easier, as we always know where the next letter will go. Previously, letters were walk-sorted but not walk-sequenced. The letters would arrive in no particular order and the postal worker had to remember where on the frame the letters should go. The skill was in knowing your frame. It would usually take a week or two before you had properly learned your frame and were up to speed.
What the new machines have done is to take away the last element of skill from our job. There\’s no memory involved any more.
That pretty much is the definition of progress. We routinise tasks, take the skilled labour out of them, mechanise them as much as possible.
This makes that skilled labour available to go off and try and solve one of the other infinite human desires and wants.
