> The problems are so many that it's better to use an alternative messaging platform that is built from the ground-up with encryption in mind, like Signal
I mostly agree. Although I don't know of something that can really replace email. Signal for example is not great for long form content, is kind of difficult to use on a desktop, is tied to your phone number, doesn't have a way to programmatically send messages (besides unsanctioned third party clients), and doesn't have a good way to group messages into conversations or threads. Most other e2e encrypted system have similar limitations.
Matrix is perhaps the most promising I've seen for replacing email. But the biggest problem is the network effect. It doesn't matter how good a system is if no one you know uses it.
