> I met an old friend the other day for board games and he spent more time playing Pokémon Go than actually interacting with me (or the board game). I told him he was being rude and he just laughed like that was absurd.

I've had similar issues with friends, girls, associates, coworkers, just about anyone.

It is a social problem, but there's an easy fix: set your boundaries, communicate them, and make it clear that this isn't acceptable (how you go about phrasing it differs on the person and their relation to you, wing it). If somehow you end up stuck with someone that can't respect your time, then maybe they're not worth your time. Setting a hardline helps me filter out different sorts that would otherwise waste my time, not just now, at this one lunch, but would continue to do so in the future.

I think it's important that as technology advances and becomes more pervasive that basic social courtesies also need to evolve in lockstep. It takes individuals to start addressing this on a case-by-case basis, but I'm optimistic that given enough people putting in enough effort that we'll get closer to the ideal of a civilized society that doesn't just know how to use their technology, but when and where it is appropriate.
