So here you have the full picture now: #PGP doesn't work and never will. Stop recommending it, stop organizing key signing parties, you aren't helping anybody doing that. Just put it to grave instead.
And #email is indeed beyond saving, I don't see secure communication over email to happen, ever. No way around establishing new protocols for encrypted communication, e.g. #Signal.

@WPalant Would an encrypted protocol that federates via DNS & routes to user mailboxes (like email) be possible though? I don't want my cell phone carrier to be in control of my netizen identity like Signal requires.
@WPalant Yes, understood. The JMAP standard working group isn't even bothering with encryption it seems. Some proprietary clients like SpikeNow.com switch to a centralized server for encrypted email which makes it easy from a user-side except both users need the same app. :-\
