Jmap is a desperately needed upgrade, but email as a whole needs to be rebuilt. The fact that it’s so core to our current infrastructure, but is really poorly suited for maybe 75% of its usage, is a bad situation that’s only going to get worse.

Of course it’s ridiculously hard to change something that’s so foundational, and I don’t trust any of the players with enough juice to pull it off (besides Google if they actually put their whole ass into it)
