I'd like to see someone solve the problem of (snail) mail.
Its the one thing that is really preventing me from living a digital nomad lifestyle. I still have to visit my office at least once a week just to pick up mail, half of which is often junk and half of which im normally too late for.
The Deutsche Post is just about to introduce email that's guaranteed to reach the addressee. https://www.onlinebrief.de/ That would invite everyone to use e-mail rather than snail, except for the (iirc) ยข20 price tag per mail.
