People keep declaring that email is broken and needs fixing. But I use it everyday and it is one of the few things in the computerised side of my life that actually does work properly.

I use Thunderbird on several machines, built in email client on my Lenovo tablet and the Gmail app on my Moto g5+. They all work. So what is it that everyone wants to fix?
