I agree. Thing is, asynchronous communication is a killer feature. My primary communications channel is email, but I don't use encrypted email.
I do use GPG, but not for email.
Although that said, and while not disagreeing about its flaws, I still can't let entirely go by:
>the protocol and the way it actually works in practice (hi, antispam!)
But anti-spam works fine with encrypted email (putting aside practicalities of no forging making spam harder anyway).
>asynchronous communication make it difficult to do encryption to the gold standard of quality
Nobody gives a shit. Asynchronous communication is well worth it.
>hope you didn't want to search your emails!
lol wut? If I go into Mail and searching something it can include encrypted emails the same as whatever else, why wouldn't it?

You can read through that if you want, frankly it kind of surprises me how nothing at all has changed since then. It's impossible not to respect Thomas immensely in this field overall, or most of his commentary. Which is why I was and remain genuinely befuddled by his replies on this specific topic. So it goes?
The idea that there isn’t an obvious replacement for email in the encrypted text communications space is a wild assertion. Brain wormy even.
Identity is the core of the matter and that is invariant of the modes of transport. On top of that comes key management. On top of that you can build your secure application on whatever platform.
Total end to end encryption can only be built on top of identity and never (ever) on a specific channel. And TE2E should be the social goal.
Email just fundamentally isn't encryptable; the protocol and the way it actually works in practice (hi, antispam!) requires that important parts of the email not be encrypted, and things like asynchronous communication make it difficult to do encryption to the gold standard of quality. Also, turning on encrypted email also disables several email features from the perspective of the user (hope you didn't want to search your emails!). The end result is that email encryption is, as someone else put it, LARPing rather than security.
There are a few very narrow use cases for which encrypted email may make sense (largely in cases where you're not concerned about hiding the existence of communication channels, just message contents, and you can do out-of-band public key communication). But notice that those use cases don't include "I want to message someone else securely," and it's definitely not someone that would work if you tried to let regular users do it.
