It's the best when I make myself feel like an idiot. "Hey moron, how long did it take you to notice this?"
Inorganics, such as metalworking, are vastly better done by manufacturing plants rather than trying to do it by hand.
Organics, such as cooking or mowing the lawn, are vastly better done using low technology.
Previously, I was modelling everything as better when done using capital-intensive methods.
The peak technology for mowing lawns is the scythe. Cooking for yourself is better than getting a restaurant to cook for you which is better than trying to buy processed factory food. Amish farming is plain better than factory farming.
Edge case: factory clothes are cheap but clothes tailored in person are vastly better, easily worth the price.
You can and should make the scythe using automated machines, but mowing done any way except quietly (and getting exercise) is the cheap, low-class way. Cheap things aren't worth their cost; if you must use a gas mower, then don't have a lawn in the first place. Skip the whole thing.
Factories are kinda not good at most things. Much like thinking machines, it seems creation machines have a few areas they're excellent (absolutely transcendent) at, but most things they're kinda bad for.
