Re: Definitely not for "after civilization ends"
Rather the opposite I think. It was intended to make it easy for signallers in the field to reliably encrypt and decrypt messages with a minimum likelihood of error. You set the wheels to the daily settings, key in the message, write down what comes out, and then start mashing the morse key. It wasn’t foolproof, but it wasn’t difficult and it was certainly a whole lot easier than doing an encryption by hand.
