With the looming threats to end to end encryption around the world, is pgp public key crytography the solution? Key exchange servers could use blockchain technology to safeguard the key exchange authenticity. Apps could be developed that work side by side with any of the main messaging apps and sideloaded if need be, that do the key exchange automatically, seemlessly, and transparently between two WhatsApp, telegram, or signal users, making it really simple for end users to bypass any backdoors that could be forced upon any of the messaging apps by governments around the world.
that should remain an option, however, the easier you make it for the end user the more likely they are to implement it, and when everyone worries about their own privacy we all win.
I doubt I'll ever see that day in my lifetime. I find GPG pretty easy to use. If I wasn't lazy I would write a GUI frontend to simplify daily use. As of now I keep batch scripts to execute commands and just add my text as needed. Most users won't do it though. Hell I can't even get friends and family to try Protonmail or Tutanota or anything along those lines. [Beating head on wall]
