There are times you need complexity enough to be worth training costs. There is one universal word "nanana", and maybe babies cry (it seems many babies have unique cries for different needs: I suspect that is training between babies and their parents - anyone done research on this?). All other language is because you spend years in training. If you can read this or write a response that implies training.

The important point from the above is it was worth the effort to learn. The only person I know who is a strong advocate of PGP was a missionary to Romania before the iron curtain fell - he had strong reason to hide what he was saying from government level actors and even today still is willing for extra effort to protect himself. For most of us though our threat profile isn't (or doesn't seem to be) that high and so learning how to use the tool isn't worth it.
