First time I hear of DeltaChat. Does it use email as the actual transport? Sounds prone to stupid latency. What's the benefit over Matrix?

[brnt]

It does, and the benefit is that anyone with an email address can already be approached via Deltachat, because all it does is send and receive email through the Autocrypt protocol, which gracefully degrades with clients that don't support it.

Gracefully degrading for clients that don’t support it is an un-goal of encrypted messaging.

You cannot read encrypted messages if you do not have gpg support. Not sure what your comment is about.

Latency is not that bad usually.
