I remember when candy canes were made by hand.
Every step… mixing, heating, rolling, stretching, and so on.
All done by people.
As each machine took its place in the line, there would be people putting things in it or taking things out of it.
But there were still people involved.
Eventually, the machines all connected to other machines, a fully integrated process, and no room was left for people.
They clean themselves now, they manage themselves, and they repair themselves too.
The candy canes taste horrible, but they look nice.
We just put them on the tree these days.
