Seems to me that if you are building computer controlled machinery you'd at least have to have a way to build the computer. The older chips, not so dense, or just a lot of circuit boards... that people can actually put together without laser alignment. A disk drive.... that sort of thing....
The list is to build a society, and that's fair enough, individual survival is not the target here. Building fires is a skill for individual survival. Building a tractor might be, though the horse drawn plow sufficed for a long time.
...but I note the absence of a paper mill. ? ... and my supply of the 8" floppy disks is pretty low.
