Email is broken. Can anybody fix it?

> "Email is bigger than Facebook. Hell, it's bigger than the internet."

Ugh..

Email is a widely successful platform of conversing that hasn't been locked into walled gardens like new forms of communication today, so I fail to see how it's broken. The article seems to set up an alarmist headline that email is broken, just to promote a (nicely designed) email app. None of the underlying protocols are changing anytime soon, nor any of them being displaced by new ones. Rather, Edison is just creating new features on their app.

At a macroscopic level, the biggest problem with email is security. It shouldn't be as difficult as it is to get encryption on emails. Sure, some tech people know how to do it easily, but for the vast public it's something they will never get done (and I'm one of those guys, even though I'm a software engineer.. I claim no expertise of neither networking nor cryptography; any recommendations for email providers?)
