As I said in another comment, it's not about everyone installing ssh and pgp and configuring them and learning how to use them, it's about us in the tech community to provide tools so easy to use you don't even know you're using state-of-the-art privacy tools. Like what Signal has done, and now it is expected that any messenger at least positions themselves on the end-to-end-encryption. Or like what Deltachat is doing with automatically configuring PGP such that users don't ever need to read those 3 dreaded letters.
