Much of what is commonly said about #email and #openpgp is wrong. It can very well be fast and secure and that's a claim backed by working code and deployments and audits (#chatmail servers and the #deltachat family of apps). There is no both-sides-have-opinions game to be played here. Internet-scale messaging alternatives are arguably either centralized or brittle. There is however much room for further improvements including deep changes in how we commonly understand email today. Stay tuned :)
