I 100% with you that UX is the most important problem that is not solved with PGP, and as long as nobody will do something we&#x27;ll never be able to use crypto. I also believe that if your crypto doesn&#x27;t solve something that PGP doesn&#x27;t already solve, then you&#x27;d better spend your time on bettering UX instead.<p>However Mumble is not a valid comparison, because Mumble is not End-to-End encrypted. The security of Mumble amounts to an encrypted connection to the server, protected by a password; from this POV Mumble is no more secure than Facebook or Hacker News.
