>If messages can be sent in plaintext, they will be sent in plaintext. I don't buy that argument. There's definitely ways to fix this, and the best example right now is Signal. I use Signal as my SMS app as well. This gives me a single interface for all my messages: For contacts without Signal, messages get exchanged as SMS. But for contacts with Signal, the conversations become end-to-end encrypted automatically. There are UI hints (Signal conversations have padlocks beside messages and a blue send button, vs a grey one) but overall it's seamless and transparent. This is totally possible with email too: look up if the receiving end has a PGP key published (PKA[1], SKS[2]) and auto-encrypt if they do. It'd be nice if we had an email client that did this.
