You should not be doing manual communications as that opens the door for human error and is time consuming. Also these cryptography protocols are far to complex to easily be used for text.
And using these apps are not always an option. I like simplex, but sometimes email is one of the only options. PGP can be used agnostic of the technology used for transmission, and that’s exactly what we need to keep more people private instead of forcing them into a few select applications. If Diffie-Helman can be used in a transport-agnostic fashion then I do not see much progress in this direction.
